SUPPLEMENT DATED JUNE 3, 2009 TO THE PROSPECTUS DATED MAY 1, 2009 OF
                           SELIGMAN PORTFOLIOS, INC.,
            ON BEHALF OF ITS SELIGMAN INTERNATIONAL GROWTH PORTFOLIO

                                (THE "PORTFOLIO")

At a Special Meeting of Shareholders held on June 2, 2009, shareholders who
owned shares of the Portfolio on April 3, 2009 approved a policy authorizing
RiverSource Investments, LLC (the Portolio's investment manager) with the
approval of the Portfolio's Board of Directors (the "Board"), to retain and
replace subadvisers, or to modify subadvisory agreements, without obtaining
shareholder approval (the "Manager of Managers Proposal").

The approval of the Manager of Managers Proposal will eliminate the need for
shareholder meetings and related proxy solicitation if the Board determines that
such retention, replacement or modification is appropriate, thereby reducing
associated costs and delays.
