Supplement  dated  October  6,  2008  to the  Prospectus  dated  May 1,  2008 of
AllianceBernstein  Variable  Products  Series Fund,  Inc. (the "Fund")  offering
Class A shares of AllianceBernstein Money Market Portfolio (the "Portfolio") and
to the  Prospectus  dated May 1, 2008 of the Fund offering Class B shares of the
Portfolio.

                                    * * * * *

On October 2, 2008,  the Board of Directors  (the  "Board") of the Fund approved
the  participation  by  the  Portfolio  in the  U.S.  Department  of  Treasury's
Temporary Guarantee Program for Money Market Funds (the "Program").  The Program
applies  to  shares of the  Portfolio  held by  shareholders  as of the close of
business as of September 19, 2008 (the "Covered Shareholders").  The Program has
an initial  three-month period (ending December 18, 2008) and it may be extended
by the Treasury for periods up to September 18, 2009.

As you know, the Portfolio seeks to maintain a stable net asset value ("NAV") of
$1.00 per share.  Subject to the limitations  discussed  below, the Program will
protect Covered  Shareholders if the Portfolio  "breaks the buck",  meaning that
its NAV falls below $.995 per share (the "Guarantee Event"). In order to qualify
for this protection,  the Portfolio must liquidate within  approximately 30 days
after the Guarantee Event. The Treasury will cover any shortfall between the NAV
at the time of liquidation and $1.00 per share.

Because  payments  under the  Program to Covered  Shareholders  are based on the
number of shares you held on September  19,  2008,  you will receive no payments
for any  increase  in the number of the  Portfolio's  shares you hold after that
date. If you sell all of your shares, you will not be covered by the Program. If
the number of shares you hold  fluctuates  due to  purchases  or sales of shares
during the Program period,  you will be covered for the number of shares held as
of the close of  business  on  September  19 or the number of shares held on the
date of the Guarantee Event,  whichever is less.  Initial purchases of shares by
new  shareholders  after  September 19 are not  eligible for coverage  under the
Program.

The Portfolio paid a fee to the Treasury for participation in the Program in the
amount of 0.01% of the Portfolio's aggregate NAV on September 19. If the Program
is extended,  the Board will consider  whether the Portfolio  should continue to
participate and, if so, the Portfolio would be required to pay additional fees.

More information about the Program is available at www.ustreas.gov.

                                    * * * * *

This  Supplement  should be read in conjunction  with the  Prospectuses  for the
