contained in documents that have been incorporated by reference by making future

automatically updated and superseded. In other words, in case of a conflict or
inconsistency between information contained in this prospectus supplement and
accompanying prospectus and information incorporated by reference into this

                           FORWARD-LOOKING STATEMENTS

     This prospectus supplement and the accompanying prospectus contain or
incorporate statements that we believe are "forward-looking statements" within
the meaning of the Private Securities Litigation Reform Act of 1995. These
statements relate to our financial condition, results of operations, plans,
objectives, future performance or business. They usually can be identified by
the use of forward-looking language such as "will likely result," "may," "are
expected to," "is anticipated," "estimate," "forecast," "projected," "intends
to" or other similar words. You should not place undue reliance on these
statements, as they are subject to risks and uncertainties, including but not
limited to those described in this prospectus supplement, the accompanying
prospectus or the documents incorporated by reference. When considering these
forward-looking statements, you should keep in mind these risks and
uncertainties, as well as any cautionary statements we may make. Moreover, you
should treat these statements as speaking only as of the date they are made and
based only on information then actually known to us.

     Our actual results, performance or achievements could be significantly
different from the results expressed in or implied by any forward-looking
statements. Factors that might cause such a difference include, but are not
limited to: (1) competitive pressures on financial institutions may increase
significantly; (2) changes in the interest rate environment may reduce interest
margins; (3) prepayment speeds, loan sale volumes, charge-offs and loan loss
provisions are inherently uncertain; (4) general economic conditions, either
national or in the states in which we do
                                       S-1


business, may be less favorable than expected; (5) political developments, wars
or other hostilities may disrupt or increase volatility in securities markets or
other economic conditions; (6) legislative or regulatory changes may adversely
affect the businesses in which we are engaged; (7) changes and trends in the
securities markets; (8) a delayed or incomplete resolution of regulatory issues;
(9) the impact of reputational risk created by these developments on such
matters as business generation and retention, funding and liquidity; and (10)
the outcome of regulatory or legal proceedings. You should refer to our periodic
and current reports filed with the SEC for further information on other factors
which could cause actual results to be significantly different from those
expressed or implied by these forward-looking statements. See "Documents
Incorporated by Reference" on page S-1 and "Where You Can Find More Information"
in the accompanying prospectus.

                                USE OF PROCEEDS

     We intend to use the net proceeds from the sale of the Notes for general
corporate purposes.

                          CONSOLIDATED EARNINGS RATIOS

     The following table provides Fifth Third's consolidated ratios of earnings
to fixed charges:



                                              THREE MONTHS        YEARS ENDED DECEMBER 31,

CONSOLIDATED RATIOS OF EARNINGS TO FIXED
  CHARGES
Excluding interest on deposits.............       5.96x       5.75x  3.24x  2.89x  3.32x  3.17x
Including interest on deposits.............       3.12        2.69   1.72   1.62   1.72   1.60

  DIVIDEND REQUIREMENTS
Excluding interest on deposits.............       5.96x       5.74x  3.24x  2.89x  3.31x  3.17x

     For purposes of computing both the consolidated ratios of earnings to fixed
charges and earnings to combined fixed charges and preferred stock dividend
requirements:

     - earnings represent net income before extraordinary items plus applicable
income taxes and fixed charges;

     - fixed charges, excluding interest on deposits, include interest expense
(other than on deposits) and the proportion deemed representative of the
interest factor of rent expense, net of income from subleases;

     - fixed charges, including interest on deposits, include all interest
expense and the proportion deemed representative of the interest factor of rent
expense, net of income from subleases; and

     - pretax earnings required for preferred stock dividends were computed
using tax rates for the applicable year.

                                       S-2


                              DESCRIPTION OF NOTES

     The Notes are a series of "subordinated debt securities" as defined in the
accompanying prospectus and will be issued under the subordinated indenture
described in that prospectus. This section summarizes the specific financial and
legal terms of the Notes that are more generally described under the section
entitled "Debt Securities" beginning on page 7 of the accompanying prospectus
(as that section relates to our subordinated debt securities). If anything
described below is inconsistent with the terms applicable to our subordinated
debt securities described under the section entitled "Debt Securities" in the
accompanying prospectus, the terms described below will prevail.

     - TITLE:  4.50% Subordinated Notes due June 1, 2018.

     - TOTAL PRINCIPAL AMOUNT BEING ISSUED:  $500,000,000.

     - MATURITY DATE:  June 1, 2018.

     - INTEREST RATE:  4.50% per annum.

     - DAY COUNT CONVENTION:  Interest will be computed on the basis of a
360-day year of twelve 30-day months.

     - DATE INTEREST STARTS ACCRUING:  May 23, 2003.

     - INTEREST PAYMENT DATES:  Every June 1 and December 1. If any interest
payment date or the maturity date of the Notes falls on a day which is not a
business day, the related payment of principal of or interest on the Notes will
be made on the next day which is a business day with the same force and effect
as if made on the date such payment was due, and no interest shall accrue on the
amount payable for the period from and after such interest payment date or
maturity date, as the case may be.

     - FIRST INTEREST PAYMENT DATE:  December 1, 2003.

     - REGULAR RECORD DATES FOR INTEREST:  Every May 15 and November 15
preceding the related interest payment date.

     - FORM OF NOTES:  The Notes will be issued as global securities, and may be
withdrawn from the Depositary only in the limited situations described on page
63 of the accompanying prospectus.

     - NAME OF DEPOSITARY:  The Depository Trust Company ("DTC").

     - TRADING IN DTC:  Indirect holders that trade their beneficial interests
in the Global Securities through DTC must trade in DTC's same-day funds
settlement system and pay in immediately available funds.

     - REDEMPTION:  The Notes are not subject to redemption at the option of
Fifth Third, or repayment at the option of the holders, in whole or in part,
prior to the maturity date.

     - SINKING FUND:  There is no sinking fund.

     - DEFEASANCE:  We may choose to terminate some of our obligations under the
Notes as described under "Defeasance and Discharge" on page 14 of the
accompanying prospectus.

     - TRUSTEE:  Fifth Third will issue the Notes under a subordinated indenture
with Wilmington Trust Company, as Trustee. As described under "Junior
Subordinated Debentures" beginning on page 45 of the accompanying prospectus,
Wilmington Trust Company also acts as trustee under our Junior Subordinated
Indenture dated as of March 20, 1997. If an event of default under the Notes
occurs, the Trustee may be considered to have a conflicting interest with
respect to the Notes or the Junior Subordinated Indenture for purposes of the
Trust Indenture Act of 1939, as

                                       S-3


amended. In that case, the Trustee may be required to resign as trustee under
the subordinated indenture and we would be required to appoint a successor
trustee.

     - SUBORDINATION:  Our obligations to make payments on the Notes will be
subordinated as described on pages 8 to 10 of the accompanying prospectus.

     - EVENTS OF DEFAULT; ACCELERATION:  An event of default under the Notes
will occur, and the payment of principal of the Notes may be accelerated, only
in certain events involving our bankruptcy, insolvency or reorganization (but
not the bankruptcy, insolvency or reorganization of any of our subsidiaries), as
more fully described on pages 11 to 12 of the accompanying prospectus. There
will be no right of acceleration of the payment of principal of the Notes upon a
default in the payment of principal or interest on the Notes or in the
performance of any of Fifth Third's covenants or agreements contained in the
Notes or in the subordinated indenture.

     - ISSUANCE OF ADDITIONAL NOTES:  We may, without notice to or consent of
the holders or beneficial owners of the Notes, issue additional notes having the
same ranking, interest rate, maturity and/or other terms as the Notes. Any such
additional notes issued may be considered part of the same series of notes under
the subordinated indenture as the Notes offered by this prospectus supplement.

                                       S-4


                                  UNDERWRITING

     Fifth Third and the underwriters for the offering (the "Underwriters")
named below have entered into an underwriting agreement with respect to the
Notes. Subject to certain conditions, each Underwriter has severally agreed to
purchase the principal amount of Notes indicated in the following table.
Goldman, Sachs & Co. and Lehman Brothers Inc. are the representatives of the
Underwriters.

UBS Warburg LLC.............................................      50,000,000
                                                                ------------
          Total.............................................    $500,000,000
                                                                ============


     The Underwriters are committed to take and pay for all of the Notes being
offered, if any are taken.

     Notes sold by the Underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus
supplement. Any Notes sold by the Underwriters to securities dealers may be sold
at a discount from the initial public offering price of up to 0.45% of the
principal amount of Notes. Any such securities dealers may resell any Notes
purchased from the Underwriters to certain other brokers or dealers at a
discount from the initial public offering price of up to 0.25% of the principal
amount of Notes. If all the Notes are not sold at the initial offering price,
the representatives may change the offering price and the other selling terms.
Underwriting discounts or commissions in connection with sales of the Notes will
not exceed 8%.

     The Notes are a new issue of securities with no established trading market.
Fifth Third has been advised by the Underwriters that the Underwriters (other
than Fifth Third Securities, Inc.) intend to make a market in the Notes but are
not obligated to do so and may discontinue market making at any time without
notice. No assurance can be given as to the liquidity of the trading market for
the Notes.

     In connection with the offering of the Notes, the Underwriters may purchase
and sell Notes in the open market. These transactions may include short sales,
stabilizing transactions and purchases to cover positions created by short
sales. Short sales involve the sale by the Underwriters of a greater number of
Notes than they are required to purchase in the offering of the Notes.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the Notes
while the offering of the Notes is in progress.

     The Underwriters also may impose a penalty bid. This occurs when a
particular Underwriter repays to the Underwriters a portion of the underwriting
discount received by it because the representatives have repurchased Notes sold
by or for the account of such Underwriter in stabilizing or short covering
transactions.

     These activities by the Underwriters may stabilize, maintain or otherwise
affect the market price of the Notes. As a result, the price of the Notes may be
higher than the price that otherwise might exist in the open market. If these
activities are commenced, they may be discontinued by the Underwriters at any
time. These transactions may be effected in the over-the-counter market or
otherwise.

                                       S-5


     Fifth Third estimates that its share of the total expenses of the offering
of the Notes, excluding underwriting discounts and commissions, will be
approximately $620,000.

     Fifth Third has agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended.

     Fifth Third Securities, Inc. is an affiliate of Fifth Third. Rule 2720 of
the Conduct Rules of the National Association of Securities Dealers, Inc.
imposes certain requirements when an NASD member such as Fifth Third Securities
distributes an affiliated company's securities. Fifth Third Securities has
advised us that this offering of the Notes will comply with the applicable
requirements of Rule 2720.

     NASD members will not confirm initial sales to accounts over which they
exercise discretionary authority without the prior specific written approval of
the customer.

     Each Underwriter has represented, warranted and agreed that: (i) it has not
offered or sold and, prior to the expiry of a period of six months from the
closing date, will not offer or sell any Notes to persons in the United Kingdom
except to persons whose ordinary activities involve them in acquiring, holding,
managing or disposing of investments (as principal or agent) for the purposes of
their businesses or otherwise in circumstances which have not resulted and will
not result in an offer to the public in the United Kingdom within the meaning of
the Public Offers of Securities Regulations 1995; (ii) it has only communicated
or caused to be communicated and will only communicate or cause to be
communicated any invitation or inducement to engage in investment activity
(within the meaning of section 21 of the Financial Services and Markets Act 2000
(the "FSMA")) received by it in connection with the issue or sale of any Notes
in circumstances in which section 21(1) of the FSMA does not apply to Fifth
Third; and (iii) it has complied and will comply with all applicable provisions
of the FSMA with respect to anything done by it in relation to the Notes in,
from or otherwise involving the United Kingdom.

     The Notes may not be offered, sold, transferred or delivered in or from The
Netherlands, as part of their initial distribution or as part of any
re-offering, and neither this prospectus supplement, the accompanying prospectus
nor any other document in respect of the offering may be distributed or
circulated in The Netherlands, other than to individuals or legal entities which
include, but are not limited to, banks, brokers, dealers, institutional
investors and undertakings with a treasury department, who or which trade or
invest in securities in the conduct of a business or profession.

                                       S-6


                             VALIDITY OF THE NOTES

     The validity of the Notes will be passed upon for Fifth Third by Paul L.
Reynolds, Esq., Executive Vice President, General Counsel and Secretary of Fifth
Third, and by Sullivan & Cromwell LLP, New York, New York. Certain legal matters
will be passed upon for the Underwriters by Sidley Austin Brown & Wood LLP, New
York, New York. Mr. Reynolds will rely as to all matters of New York law upon
the opinion of Sullivan & Cromwell LLP, and Sullivan & Cromwell LLP and Sidley
Austin Brown & Wood LLP will rely as to all matters of Ohio law upon the opinion
of Mr. Reynolds.

                                    EXPERTS

     The consolidated financial statements of Fifth Third, except the amounts
included for Old Kent Financial Corporation, incorporated in this prospectus
supplement by reference to Fifth Third's Annual Report on Form 10-K for the year
ended December 31, 2002 have been audited by Deloitte & Touche LLP, independent
auditors, as stated in their report (which report expresses an unqualified
opinion and includes an explanatory paragraph referring to Fifth Third's
adoption of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets," as discussed in Note 1 to the consolidated financial
statements), which is also incorporated by reference, and have been so
incorporated in reliance upon the report of such firm given upon their authority
as experts in accounting and auditing.

     The separate financial statements of Old Kent Financial Corporation as of
and for the year ended December 31, 2000 consolidated with those of Fifth Third
and not presented separately, have been audited by Arthur Andersen LLP,
independent public accountants, as indicated in their report issued on January
17, 2001. Arthur Andersen consented to the inclusion of its report in our Annual
Report on Form 10-K for the year ended December 31, 2001 and its incorporation
by reference into the registration statement of which the prospectus forms a
part. The report has not been reissued by Arthur Andersen since January 17, 2001
nor has Arthur Andersen consented to the inclusion of the report in our Annual
Report on Form 10-K for the year ended December 31, 2002.

     Arthur Andersen was convicted on June 15, 2002 of federal obstruction of
justice in connection with its actions regarding Enron Corp. and ceased to
practice before the Securities and Exchange Commission as of August 31, 2002. As
a result of the events arising out of Arthur Andersen's conviction you may have
no effective remedy against it in connection with a material misstatement or
omission in the financial statements it audited. Moreover, the events arising
out of Arthur Andersen's conviction may adversely affect the ability of Arthur
Andersen to satisfy any successful claim.
