Prospectus Supplement No. 6 to
Prospectus dated November 24, 2003

$511,015,000 Balance at Maturity of
Senior Convertible Notes due 2033

5,877,490 shares of
Common Stock

        We are supplementing our prospectus dated November 24, 2003, which we refer to as the base prospectus. References to the prospectus include the base prospectus and all supplements to the base prospectus, collectively.

        You should read this prospectus supplement together with the base prospectus and all other supplements to the base prospectus. The base prospectus and all prospectus supplements are to be delivered with any prospectus supplement. Please see “Where You Can Find More Information” in the base prospectus for a listing of the documents incorporated and deemed to be incorporated by reference in the prospectus. This prospectus supplement is not complete without, and may not be delivered or utilized except in connection with, the base prospectus, including all amendments and supplements thereto. The terms of the convertible debentures are set forth in the base prospectus.

        The prospectus relates to $511,015,000 balance at maturity of Senior Convertible Notes due 2033 of American Financial Group, Inc. which were sold by American Financial Group during June 2003. The prospectus also relates to 5,877,490 shares of American Financial Group common stock issuable upon conversion of the notes held by selling securityholders, plus such additional indeterminate number of shares as may become issuable upon conversion of the notes by reason of adjustment to the conversion price in certain circumstances.

        Investing in the notes involves risks, see “Risk Factors” beginning on page 11 of the base prospectus.

        Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

        The date of this prospectus supplement is October 21, 2004


        The information appearing under the section entitled “Selling Securityholders” in the prospectus is amended and restated by the information appearing below.

SELLING SECURITYHOLDERS

        The notes originally were issued by us and sold by Merrill Lynch, Pierce, Fenner & Smith Incorporated, UBS Securities LLC and Credit Suisse First Boston LLC, as the initial purchasers, in transactions exempt from the registration requirements of the Securities Act of 1933 to persons reasonably believed by the initial purchasers to be qualified institutional buyers.

        The selling securityholders may offer all, some or none of the notes and the common stock.

        The table below sets forth the name of each selling securityholder, the principal amounts of notes that may be offered by each selling securityholder under this prospectus and the number of shares of common stock into which the notes are convertible. The notes and the underlying common stock set forth below includes securities that may be sold by pledgees, donees, transferees or other successors in interest to the selling securityholders that receive such securities by pledge, gift, distribution or other non-sale related transfer from the named selling securityholders. The information is based on information provided to us by or on behalf of the selling securityholders on or prior to October 21, 2004.

        The selling securityholders identified below may have sold, transferred or otherwise disposed of all or a portion of their notes or common stock since the date on which they provided this information in transactions exempt from the registration requirements of the Securities Act. Information about the selling securityholders may change from time to time. Any changed information will be set forth in prospectus supplements or post-effective amendments, as required.

        Because the selling securityholders may offer all or some portion of the notes or the common stock into which the notes are convertible, we cannot estimate the amount of notes or common stock that may be held by the selling securityholders upon the completion of any sales. For information on the procedure for sales by selling securityholders, read the disclosure under the heading “Plan of Distribution” in the prospectus.

      * Less than 1%

    (1)        No selling securityholder beneficially owns 1% or more of our outstanding common stock, and no selling securityholder will beneficially own 1% or more of our outstanding common stock after the offering of the common stock acquirable upon conversion of the notes.

    (2)        Assumes conversion of all of the selling securityholder’s notes at a conversion rate of 11.5016 shares of common stock per $1,000 aggregate principal amount of notes and a cash payment in lieu of the issuance of any fractional share interest. However, this conversion rate is subject to adjustment as described under “Description of the Notes—Conversion Rights” in the base prospectus. As a result, the number of shares of common stock issuable upon conversion of the notes may increase or decrease in the future.

    (3)        Reflects rounding down of fractional shares of common stock issuable to each selling securityholder upon conversion of the notes.

    (4)        Such selling securityholder has represented to us that it is an affiliate of a broker-dealer. Based solely on written representations received from such selling securityholder, we understand that such entities acquired their notes or underlying common stock in the ordinary course of business and, at the time of the purchase of the notes or the underlying common stock, such selling securityholders had no agreements or understandings, directly or indirectly, with any person to distribute the notes or underlying common stock. To the extent that we become aware that such entities did not acquire their notes or underlying common stock in the ordinary course of business or did have such an agreement or understanding, we will file a post-effective amendment to the registration statement of which the prospectus forms a part to designate such affiliate as an “underwriter” within the meaning of the Securities Act.

    (5)        Table does not include information for selling securityholders that had not submitted information through October 21, 2004.

        None of the selling securityholders listed above has, or within the past three years had, any position, office or any material relationship with us or any of our affiliates.

        Only selling securityholders identified above who beneficially own the notes set forth opposite each such selling securityholder’s name in the foregoing table on the effective date of the registration statement, of which this prospectus forms a part, may sell such securities pursuant to the registration statement. Prior to any use of this prospectus in connection with an offering of the notes or the underlying common stock by any holder not identified above, we will file a further post-effective amendment to the registration statement, of which this prospectus forms a part, to set forth the name and aggregate amount of notes beneficially owned by the selling securityholder intending to sell such notes or the underlying common stock and the aggregate amount of notes or the number of shares of the underlying common stock to be offered. The prospectus, as supplemented, will also disclose whether any selling securityholder selling in connection with such prospectus has held any position or office with, has been employed by or otherwise has had a material relationship with us during the three years prior to the date of the prospectus if such information has not been disclosed herein.

Item 17.    Undertakings.

(a)     The undersigned Registrant hereby undertakes:

    (1)        To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

    (i)        To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;


    (ii)        To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement.


    (iii)        To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;


Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement.

    (2)        That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

    (3)        To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)     The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual reports pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
