PROSPECTUS SUPPLEMENT
(To the Prospectus dated May 2, 2016)
US$750,000,000
Bancolombia S.A.
4.875% Subordinated Notes due 2027



We are offering US$750,000,000 of our 4.875% subordinated Notes due 2027 (the "Notes"). The Notes will mature on October 18, 2027. The Notes will bear
interest at 4.875% per year from and including the issuance date of the Notes to, but excluding, the Reset Date. From and after the Reset Date to, but excluding, the date
of maturity or earlier redemption date of the Notes, the Notes will bear interest on the outstanding principal amount at a rate per annum equal to the sum of (i) the
Benchmark Reset Rate on the Reset Date plus (ii) 292.9 basis points as calculated by the issuer. Interest is payable semi-annually, in arrears, on and of each year,
beginning April 18, 2018. The Notes will be subject to redemption prior to the maturity date, as further described herein.

UPON THE OCCURRENCE OF A WRITE-DOWN EVENT, AS DEFINED HEREIN, THE OUTSTANDING PRINCIPAL AMOUNT OF THE NOTES,
INTEREST AND ADDITIONAL AMOUNTS, IF ANY, MAY BE PERMANENTLY REDUCED TO THE EXTENT REQUIRED TO RESTORE OUR
CAPITAL RATIOS. NO INTEREST WILL ACCRUE ON ANY PRINCIPAL AMOUNT OF THE NOTES THAT IS SO REDUCED. IF A WRITE-DOWN
EVENT OCCURS, YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT.

The Notes will be our unsecured subordinated obligations and will rank junior to all of our existing and future senior obligations and will rank senior only to our
capital stock and any other instrument that may qualify as Tier One Capital for purposes of Colombian banking laws, if any, and which is expressly or effectively
subordinated to the Notes. The Notes will not be guaranteed by our subsidiaries and will not be entitled to any sinking fund.

We will apply to list the Notes on the New York Stock Exchange (the "NYSE"). Currently, there is no public market for the Notes.

Investment in the Notes involves risks. See "Risk Factors" beginning on page S-8 of this prospectus supplement to read about certain risk factors you
should consider before investing in the Notes.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or
adequacy of this prospectus supplement and accompanying prospectus. Any representation to the contrary is a criminal offense.

The Notes are not intended to be sold and should not be sold to retail clients in the EEA, as defined in the rules set out in the Product Intervention
(Contingent Convertible Instruments and Mutual Society Shares) Instrument 2015, as amended or replaced from time to time, other than in circumstances
that do not and will not give rise to a contravention of those rules by any person. Prospective investors are referred to the section headed "Restrictions on
marketing and sales to retail investors" on page i of this prospectus supplement for further information.

THE INFORMATION SUBMITTED TO THE SUPERINTENDENCIA FINANCIERA DE COLOMBIA (THE COLOMBIAN SUPERINTENDENCY OF
FINANCE) AND THE POTENTIAL QUALIFICATION OF THE NOTES AS TIER TWO CAPITAL WILL NOT CONSTITUTE AN OPINION OF THE
COLOMBIAN SUPERINTENDENCY OF FINANCE WITH RESPECT TO APPROVAL OF THE QUALITY OF THE NOTES OR OUR SOLVENCY. THE NOTES
MAY NOT BE PUBLICLY OFFERED OR SOLD IN THE REPUBLIC OF COLOMBIA.

Restrictions on marketing and sales to retail investors

The Notes are complex financial instruments and are not a suitable or appropriate investment for all investors. In some jurisdictions, regulatory authorities have
adopted or published laws, regulations or guidance with respect to the offer or sale of securities such as the Notes to retail investors.

In particular, in June 2015, the U.K. Financial Conduct Authority (the "FCA") published the Product Intervention (Contingent Convertible Instruments and
Mutual Society Shares) Instrument 2015, which took effect from 1 October 2015 (the "PI Instrument").

Under the rules set out in the PI Instrument (as amended or replaced from time to time, the "PI Rules"):

(i) certain contingent write-down or convertible securities (including any beneficial interests therein), such as the Notes, must not be sold to retail clients in
the EEA; and

(ii) there must not be any communication or approval of an invitation or inducement to participate in, acquire or underwrite such securities (or the beneficial
interest in such securities) where that invitation or inducement is addressed to or disseminated in such a way that it is likely to be received by a retail client in
the EEA (in each case, within the meaning of the PI Rules), other than in accordance with the limited exemptions set out in the PI Rules.

Certain of the underwriters or their affiliates are required to comply with the PI Rules. By purchasing, or making or accepting an offer to purchase, any Notes
(or a beneficial interest in such Securities) from the Issuer and/or the underwriters, each prospective investor represents, warrants, agrees with and undertakes to the
Issuer and each of the underwriters that:

1. it is not a retail client in the EEA (as defined in the PI Rules);

2. whether or not it is subject to the PI Rules, it will not

(A) sell or offer the Notes (or any beneficial interest therein) to retail clients in the EEA or

(B) communicate (including the distribution of this prospectus supplement or approve an invitation or inducement to participate in, acquire or
underwrite the Notes (or any beneficial interests therein) where that invitation or inducement is addressed to or disseminated in such a way that it is
likely to be received by a retail client in the EEA (in each case within the meaning of the PI Rules),

in any such case other than (i) in relation to any sale or offer to sell Notes (or any beneficial interests therein) to a retail client in or resident in the United
Kingdom, in circumstances that do not and will not give rise to a contravention of the PI Rules by any person and/or (ii) in relation to any sale or offer to sell
Notes (or any beneficial interests therein) to a retail client in any EEA member state other than the United Kingdom, where (a) it has conducted an assessment
and concluded that the relevant retail client understands the risks of an investment in the Notes (or such beneficial interests therein) and is able to bear the
potential losses involved in an investment in the Notes (or such beneficial interests therein) and (b) it has at all times acted in relation to such sale or offer in
compliance with the Markets in Financial Instruments Directive (2004/39/EC) ("MiFID") to the extent it applies to it or, to the extent MiFID does not apply to
it, in a manner which would be in compliance with MiFID if it were to apply to it; and

3. it will at all times comply with all applicable laws, regulations and regulatory guidance (whether inside or outside the EEA) relating to the promotion,
offering, distribution and/or sale of the Notes (or any beneficial interests therein), including (without limitation) any such laws, regulations and regulatory
guidance relating to determining the appropriateness and/or suitability of an investment in the Notes (or any beneficial interests therein) by investors in any
relevant jurisdiction.

Where acting as agent on behalf of a disclosed or undisclosed client when purchasing, or making or accepting an offer to purchase, any Notes (or any beneficial interests
therein) from the Issuer and/or the underwriters, the foregoing representations, warranties, agreements and undertakings will be given by and be binding upon both the
agent and its underlying client.

EXCHANGE RATES

This prospectus supplement converts certain peso amounts into U.S. dollars at specified rates solely for the convenience of the reader. The Federal Reserve
Bank of New York does not report a rate for pesos. Unless otherwise indicated, such peso amounts have been converted at the rate of COP 3,050.43 per US$1.00, which
corresponds to the tasa representativa del mercado ("representative market rate") calculated on June 30, 2017. The representative market rate is computed and certified
by the Superintendencia Financiera de Colombia, the Colombian Superintendency of Finance (the "SFC"), on a daily basis and represents the weighted average of the
buy/sell foreign exchange rates negotiated on the previous day by certain financial institutions authorized to engage in foreign exchange transactions (including us). The
SFC also calculates and certifies the average representative market rate for each month for purposes of preparing financial statements and converting amounts in foreign
currency to pesos. You should not construe these convenience conversions as a representation that the peso amounts correspond to, or have been or could be converted
into, U.S. dollars at the representative market rate or any other rate.On June 30, 2017 and June 30, 2016, the representative market rate was COP 3,050.43 and 2,919.01
per US$1.00, respectively, as published on July 4, 2017 and July 1, 2016, respectively. On September 22, 2017, the representative market rate was COP 2,900.73 per
US$1.00, as published on September 25, 2017.

The following table sets forth the low and high peso per U.S. dollar exchange rates and the peso/U.S. dollar representative market rate on the last day of the
month, for each of the last six months:

ENFORCEMENT OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS

We are a Colombian company, a majority of our directors and management and certain of the experts named in this prospectus supplement are residents of
Colombia, and a substantial portion of their respective assets are located in Colombia.

We have been advised by Brigard & Urrutia, our Colombian counsel, that the Supreme Court of Justice of Colombia (Corte Suprema de Justicia de Colombia),
determines whether to enforce a U.S. judgment predicated on the U.S. securities laws through a procedural system known under Colombian law as exequatur. The
Supreme Court of Justice of Colombia will enforce a foreign judgment, without reconsideration of the merits, only if the judgment satisfies the requirements of articles
605 through 607 of Law 1564 of 2012, (Código General del Proceso), which provide that the foreign judgment will be enforced if:

1.
A treaty or convention exists between Colombia and the country where the judgment was granted or there is reciprocity in the recognition of foreign
judgments between the courts of the relevant jurisdiction and the courts of Colombia;

2.
The foreign judgment does not relate to "in rem rights" vested in assets that were located in Colombia at the time the suit was filed;

3.
The ruling does not contradict Colombian laws relating to public order other than those governing judicial procedures;

4.
The foreign judgment, in accordance with the laws of the country where it was rendered, is final and is not subject to appeal and a duly legalized copy of
the judgment has been presented to a competent court in Colombia;

5.
The foreign judgment does not refer to any matter upon which Colombian courts have exclusive jurisdiction;

6.
No proceeding is pending in Colombia with respect to the same cause of action, and no final judgment has been awarded in any proceeding in Colombia
on the same subject matter and between the same parties; and

7.
In the proceeding commenced in the foreign court that issued the judgment, the defendant was served in accordance with the law of such jurisdiction and
in a manner reasonably designated to give the defendant an opportunity to defend against the action.

In the course of the exequatur proceedings, both the plaintiff and the defendant are granted the opportunity to request the production of evidence in connection
https://www.sec.gov/Archives/edgar/data/1071371/000114420417052287/tv476863_424b5.htm[10/13/2017 9:42:53 AM]


with the requirements listed above. In addition, before the judgment is rendered, each party may file final allegations in support of such party's position. The United
States and Colombia do not have a bilateral treaty providing for automatic reciprocal recognition and enforcement of judgments in civil and commercial matters.
However, the Colombian Supreme Court has generally accepted that reciprocity exists when it has been proven that either a U.S. court has enforced a Colombian
judgment or that a U.S. court would enforce a foreign judgment, including a judgment issued by a Colombian court. Nevertheless, such enforceability decisions are
considered by Colombian courts on a case-by-case basis.

Colombia is party to international treaties such as the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the "New
York Convention"), the 1975 Inter-American Convention on International Commercial Arbitration, and the 1965 Washington Convention for the Settlement of Disputes
between States and Nationals of Other States.

As of the enactment of Law 1563 of 2012, in force as of October 13, 2012, international arbitration awards issued by arbitral tribunals sitting in Colombia are
not subject to exequatur or recognition proceedings to be recognized, except when the parties waived their right to request the annulment of the award.

Recognition of international arbitration awards may only be denied pursuant to the grounds described in article 112 of Law 1563 of 2012:

when it is proved by the party against which recognition is sought that:

·
the party to the arbitration agreement was, under the applicable law, under some incapacity, or said agreement is not valid; or

·
the party against whom the award is enforced was not given proper notice of the appointment of an arbitrator or of the initiation of the arbitration
proceeding or was otherwise unable to present its rights in the case; or

·
the subject matter of the award is a dispute not included within the terms of the submission to arbitration or it contains decisions on matters beyond the
scope of the arbitration agreement (if the decisions on matters submitted to arbitration can be separated from those not submitted, the first may be
recognized and enforced); or

·
the integration of the arbitration tribunal or the arbitral procedure was not in accordance with the agreement of the parties, or in accordance with the law of
the country where the arbitration took place; or

·
the award is not yet binding become binding for the parties or was annulled or suspended by an authority of the country in which the award was issued; or


-vii-



when the competent judicial authority verifies that:

·
in accordance with Colombian law, the matter may not be subject to arbitration; or

·
the recognition or enforcement of the award would be contrary to Colombian international public policy.

If there is an annulment petition or a motion for suspension filed before a judicial authority of the country where the arbitration is located, then the Colombian
judicial authorities may suspend of its ruling on the award's recognition.

The above events are similar to the ones regulated in articles V and VI of the New York Convention.

Our consolidated net income attributable to equity holders of the parent company for the year ended December 31, 2016 and for the six months ended June
30, 2017 was COP 2,865 billion and COP 1,262 billion, respectively, representing an annualized average return on equity attributable to the owners of the parent
company of 14.52% and 11.80%, respectively, and an annualized average return on assets of 1.49% and 1.30%, respectively.

We are a stock company (sociedad anónima) domiciled in Medellín, Colombia, and we operate under Colombian laws and regulations, principally the
Colombian Code of Commerce, Decree 663 of 1993 and Decree 2555 of 2010, as amended. We were incorporated in Colombia in 1945 under the name Banco
Industrial Colombiano S.A. or "BIC". In 1998, we merged with Banco de Colombia S.A., and changed our legal name to Bancolombia S.A. On July 30, 2005,
Conavi and Corfinsura merged with and into Bancolombia, with Bancolombia as the surviving entity. Through this merger, Bancolombia gained important
competitive advantages, as Conavi and Corfinsura were two of the top financial institutions in the Colombian market at the time. Conavi, a mortgage bank in
Colombia and one of the strongest in retail operations, significantly increased the Bank's participation and know-how in these specific markets. On the other hand,
Corfinsura, then the largest financial corporation in Colombia and highly regarded for its expertise in handling large and mid-sized corporate credit loans and
financial services, its investment bank and its modern and diversified treasury department, significantly strengthened our full service franchise.

In May 2007, Bancolombia Panamá acquired Banagrícola S.A., which controls several subsidiaries, including Banco Agrícola S.A. ("Banco Agrícola") in
El Salvador, and is dedicated to banking, commercial and consumer activities, insurance and brokerage. Through this first international acquisition, we gained a
leadership position in the Salvadorian financial market.

In October 2013, we acquired a 100% percent interest of the outstanding equity of Banistmo, a Panamanian banking entity and its subsidiaries involved in
the securities brokerage, trust, consumer finance, and leasing businesses in Panama.

Also in October 2013, our wholly-owned subsidiary Bancolombia Panama acquired a 40% interest in Grupo Agromercantil, the parent company of Banco
Agromercantil de Guatemala, and certain other companies dedicated to securities brokerage, insurance, and other financial businesses in Guatemala. Bancolombia
Panama acquired an additional 20% interest and control of Grupo Agromercantil on December 30, 2015.

Since 1995, we have maintained a listing on the NYSE, where our ADSs are traded under the symbol "CIB", and on the Colombian Stock Exchange, where
our preferred shares are traded under the symbol "PFBCOLOM." Since 1981, our common shares have been traded on Colombian exchange under the symbol
"BCOLOMBIA."

Strategy

Throughout its history, Bancolombia has executed a strategy that has allowed it to create a platform for growth. This strategy has been evidenced in the
creation of a universal banking model, in local and international acquisitions to expand its market, in access to the main capital markets of the world, in the creation
of a physical network with ample coverage, and in the consolidation of one of the most valuable and reputable brands in Colombia.

Our strategic aspiration is to be the leading financial group that sets the trend, generating a superior experience for its customers, pride for its employees and
value for its shareholders, in a sustainable way.

The main objectives of Bancolombia's strategy for the medium term are:

solutions and promote efficient decision-making processes.

Maintain operational excellence by focusing on process optimization, re-balancing our branch network, continuing strict cost control across
divisions and countries, and enhancing our offering of digital services to clients.

funds without the need for physical infrastructure, and managing our interest rate risk to protect our net interest margin.

Issuer
Bancolombia S.A.


Securities Offered
US$750,000,000 in aggregate principal amount of 4.875% Subordinated Notes due 2027.


Issue Price
100.000% of the principal amount of the Notes, plus accrued interest, if any from October 18, 2017.

Interest

offering to, but excluding, the Reset Date.

From and after the Reset Date to, but excluding, the date of maturity or earlier redemption date of the

sum of (i) the Benchmark Reset Rate on the Reset Date plus (ii) 292.9 basis points as calculated by the
issuer.

Interest will be payable semi-annually, in arrears, on April 18 and October 18 of each year, beginning on
April 18, 2018.

In the event that we default on the payment of principal, premium, if any, interest or such other amounts
as may be payable in respect of the Notes, we will pay interest on overdue principal and premium, if
any, at the rate borne by the Notes plus 1% per year and will pay interest on overdue installments of
interest at the same rate to the extent lawful.


Loss Absorption; Reduction of Principal, Interest and Other The Notes provide that, as determined by applicable Colombian laws and regulations then in effect, if:
Amounts
(i) our Basic Individual Solvency Ratio or our Basic Consolidated Solvency Ratio (as such terms are
defined in "Description of the Notes") is below 4.5%; or (ii) if the SFC, in its discretion, otherwise so
determines in writing, the outstanding principal, accrued and unpaid interest, and any other amounts due
on the Notes will be permanently reduced, pro rata with reductions in the outstanding principal, accrued
and unpaid interest and any other amount due on other Tier Two Capital subordinated Indebtedness as to
which a Write-Down Event (as defined in "Description of the Notes") has occurred, if any, (other than
subordinated Indebtedness, that, under its terms, is designated as junior to the Notes) by an amount
needed to (x) restore the Basic Individual Solvency Ratio to 6%; (y) restore the Basic Consolidated
Solvency Ratio to 6%; or (z) comply with the order of the SFC to restore the Basic Individual Solvency
https://www.sec.gov/Archives/edgar/data/1071371/000114420417052287/tv476863_424b5.htm[10/13/2017 9:42:53 AM]


Ratio or Basic Consolidated Solvency Ratio to 6%, as applicable; provided, that the principal amount of
the Notes may not be written down below zero. Furthermore, any such reduction will not constitute an
Event of Default under the Notes.

As of the date of their initial issuance, the Notes will be the only debt securities we have that include the
loss absorption feature described above. If a Write-Down Event occurs, holders of the Notes may
suffer a permanent loss of some or all of their principal, interest or other amounts due on the
Notes. No interest will accrue on any amount of principal reduced as a result of a Write-Down
Event, and the occurrence of a Write-Down Event will not constitute an Event of Default.


Form and Denomination
The Notes will be issued in registered form, without coupons, and in minimum denominations of
US$200,000 and integral multiples of US$1,000 in excess thereof.


Payment Currency
All amounts due in respect of principal, interest or the additional amounts, if any, will be paid in U.S.
dollars.


Ranking
The Notes will be our unsecured subordinated obligations. In the event of our liquidation under
Colombian law, the Notes will rank:



· junior in right of payment to the prior payment in full of all our existing and future Senior
External Liabilities (as defined in "Description of the Notes"). As of June 30, 2017, we have
COP171,910.31 billion of Senior External Liabilities;



· pari passu with all our other present or future Tier Two Capital subordinated Indebtedness (as
defined in "Description of the Notes") other than subordinated Indebtedness, that, under its
terms, is designated as junior to the Notes. As of June 30, 2017, we have COP 7,633.88 billion
of outstanding Tier Two Capital subordinated Indebtedness; and


S-3




· senior in right of payment only to subordinated instruments constituting Tier One Capital (of
which we currently have none outstanding) and our capital stock.

As a result of the operation of the provisions of the Notes described under "Description of the Notes--
Loss Absorption", Holders may recover less ratably than holders of pari passu subordinated debt of the
Bank that does not include a similar loss absorption feature. As of June 30, 2017, after giving pro forma
effect to the offering of Notes and the completion of the Tender Offer (assuming that tenders of Old
Notes are accepted on the Early Tender Date for an aggregate purchase amount equal to the Aggregate
Maximum Tender Consideration), we would have had approximately COP5,583 billion aggregate
principal amount of subordinated indebtedness that does not include a similar loss absorption feature.

Optional Redemption
At our option, in whole but not in part, on the Reset Date, at a redemption price equal to 100% of the
outstanding aggregate principal amount thereof, plus accrued and unpaid interest and Additional
Amounts, if any, to, but excluding, the date of redemption, subject to certain conditions, including prior
approval of the SFC if so required at the time of redemption (as further described in "Description of the
Notes").


Optional Redemption upon Tax or Regulatory Event
The following optional redemption rights are not permitted under current Colombian regulations.
We will not be able to exercise these optional redemption rights unless regulations are
implemented permitting us to do so.

Notwithstanding the foregoing, and provided that regulations are implemented that permit us to do so, at
any time after the Issue Date (as defined in the "Description of the Notes") and subject to certain
conditions, we may redeem the Notes in whole, but not in part, at a price equal to 100% of the
outstanding principal amount thereof plus accrued and unpaid interest and any Additional Amounts, to
the relevant date of redemption, following the occurrence of a Regulatory Event or a Tax Event. See
"Description of the Notes--Optional Redemption upon Tax Event or Regulatory Event."

Merger and Sales of Assets
The indenture governing the Notes will contain a covenant that limits our ability to merge or consolidate
with another entity or sell, lease or transfer substantially all of our properties or assets to another entity.
See "Description of the Notes--Certain Covenants--Mergers, Consolidations, Etc."


Limitation on Acceleration of Notes
If we fail to make payment of principal, interest or Additional Amounts, if any, on the Notes (and, in the
case of payment of principal, such failure to pay continues for seven days or, in the case of payment of
