EXHIBIT 99.4


                                             March 17, 1997



Dear Participant::

As of March 5, 1997, the trust ("ESOP Trust") established for the
Columbia Federal Savings Bank (the "Bank") Employee Stock Ownership
Plan ("ESOP") held 343,227 shares of common stock of Haven Bancorp,
Inc. (the "Company"), the parent holding company for the Bank, for
the benefit of participants in the ESOP.  As a participant in the
ESOP, you may direct the voting of the shares of the Company's
common stock held by the ESOP Trust allocated to your account.

An unrelated corporate trustee for the ESOP has been appointed,
ChaseMellon Shareholder Services L.L.C. (the "ESOP Trustee").  We,
the Board of Directors, are forwarding to you the attached Vote
Authorization Form, provided for the purpose of conveying your
voting instructions to the ESOP Trustee.  The ESOP Trustee will
vote those shares of the Company's common stock held in the ESOP
Trust allocated to participants in accordance with instructions of
the participants.

As of the Record Date, March 5, 1997, 123,502 shares of Common
Stock in the ESOP had been allocated to participating employees. 
The ESOP Trustee will vote the allocated shares held in the ESOP
Trust in accordance with instructions of the participants.  All
unallocated shares held in the ESOP Trust, and allocated shares
with respect to which no written instructions are received, will be
voted by the Trustee in the same proportion as those allocated
shares for which voting instructions are received, so long as such
vote is in accordance with the provisions of the Employment
Retirement Income Security Act of 1974, as amended.

At this time, in order to direct the voting of shares allocated to
your account under the ESOP, you must fill out and sign the
enclosed Vote Authorization Form and return it in the accompanying
envelope.  Your vote will not be revealed, directly or indirectly,
to any director, officer or other employee of the Company or the
Bank.  Your shares will be tallied by an independent source and
then the ESOP Trustee will vote the shares in the ESOP Trust based
on the voting instructions it has received from participants, as
described above.

                                        Sincerely,



                                        The Board of Directors



                    HAVEN BANCORP, INC.
