Boston, Massachusetts 02109

Ladies and Gentlemen:

     We are furnishing this opinion in connection with the sale
during the fiscal year ended September 30, 1996 of 10,931,707,218
shares of beneficial interest (the "Shares") of Putnam Money
Market Fund.

     We have examined copies of (i) your Agreement and
Declaration of Trust as on file at the office of the Secretary of
State of The Commonwealth of Massachusetts, which provides for an
unlimited number of authorized shares of beneficial interest, and
(ii) your Bylaws, which provide for the issue and sale by the
Fund of such Shares.  We have also examined (i) a copy of the
notice (the "Notice") to be filed pursuant to the Rule by you
with the Securities and Exchange Commission relating to your
registration of an indefinite number of shares of beneficial
interest of the Fund pursuant to the Securities Act of 1933, as
amended, and making definite registration of the Shares pursuant
to the Rule, and (ii) a certificate of the Treasurer of the Fund
stating that all of the Shares had been recorded as issued and
that the appropriate consideration therefore as provided in your
Bylaws had been received at September 30, 1996.

     We assume that appropriate action has been taken to register
or qualify the sale of the Shares under any applicable state and
federal laws regulating offerings and sales of securities, and
that the Notice will be timely filed with the Securities and
Exchange Commission.

     Based upon the foregoing, we are of the opinion that:

     1.  The Fund is a legally organized and validly existing
voluntary association with transferable shares of beneficial
interest under the laws of The Commonwealth of Massachusetts and
is authorized to issue an unlimited number of shares of
beneficial interest.

     2.  The Shares were validly issued and fully paid and
nonassessable by the Fund at September 30, 1996.

     The Fund is an entity of the type commonly known as a
Massachusetts business trust.  Under Massachusetts law,
shareholders could, under certain circumstances, be held
personally liable for the obligations of the Fund.  However, the
Agreement and Declaration of Trust disclaims shareholder
liability for acts or obligations of the Fund and requires that
notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by the Fund or its
Trustees.  The Agreement and Declaration of Trust provides for
indemnification out of the property of the Fund for all loss and
expense of any shareholder of the Fund held personally liable for
the obligations of the Fund solely by reason of his being or
having been a shareholder of the Fund.  Thus, the risk of a
shareholder incurring financial loss on account of shareholder
liability is limited to circumstances in which the Fund itself
would be unable to meet its obligations.

     We consent to this opinion accompanying the Notice.

                              Very truly yours,

                              /s/ Ropes & Gray
