Exhibit 21.1

                        Subsidiaries of the Registrant

     There are currently no subsidiaries of Port Financial Corp. (the
"Registrant"). Following the conversion of Cambridgeport Mutual Holding Company
(the "MHC") from a Massachusetts mutual holding company into a Massachusetts
stock holding company, the Registrant will have two wholly-owned subsidiaries:
Cambridgeport Bank, a Massachusetts-chartered stock savings bank; and Brighton
Investments Corp., a Massachusetts securities corporation.
