Item 7.01  Regulation FD Disclosure.

The  Board  of  Directors  (the  "Board")  of  Ames  National  Corporation  (the
"Company"),  at a meeting held on May 11, 2005,  approved a three-for-one  stock
split of the  Company's  common stock under which each holder of common stock as
of the  record  date for the  stock  split  would be  entitled  to  receive  two
additional shares of common stock for each one share of common stock owned as of
such record date.  The purpose of the stock split is to reduce the trading price
of the common stock to a range that will be more  attractive  to  investors.  To
accommodate the stock split, the Board also adopted an amendment to the Restated
Articles of Incorporation  of the Company (the "Restated  Articles") to increase
the Company's  authorized  capital stock from 6 million to 18 million  shares of
common  stock and reduce the par value of the common  stock from $5.00 per share
to $2.00 per share.  The proposed  amendment to the  Restated  Articles  will be
submitted to the  shareholders for approval at a special meeting of shareholders
to be held on June  15,  2005.  The  proposed  stock  split is  contingent  upon
approval  of the  amendment  to  Restated  Articles,  as the  Company  would not
otherwise  have a sufficient  number of authorized  shares to complete the stock
split.  If the  amendment is approved by the  shareholders,  the record date and
effective date for the stock split will be publicly  announced by the Company in
accordance with the rules of the NASDAQ SmallCap Market.

The Board also adopted proposed amendments to the Restated Articles to implement
certain provisions relating to limitation of liability of directors for monetary
damages and  indemnification  of directors  and officers as authorized by recent
amendments  to the  Iowa  Business  Corporation  Act.  If these  amendments  are
approved  by  the  shareholders  at the  special  meeting,  the  indemnification
provisions  currently  contained  in Article 9 of the  Company's  bylaws will be
repealed and replaced by the  indemnification  provision  adopted as part of the
Restated Articles.

The  Board  also  took  action to cancel  16,164  shares  of common  stock  that
previously  had been held as  treasury  stock,  with the effect that such shares
have now been returned to the status of authorized but unissued shares.
