St. Catherine's Greek Orthodox Church, formerly home to the Wollaston Unitarian Church, is a historic church building at 155 Beale Street in Quincy, Massachusetts. The Shingle style building was built in 1888 for a Unitarian congregation established the previous year. The Wollaston Church merged with United First Parish Church in Quincy in 1960. The Beale Street building was purchased for $40,000 by St. Catherine's Greek Orthodox Church of the South Shore. St. Catherine's grew over the years, and in 2004 the congregation moved to a new building in Braintree. The building was added to the National Register of Historic Places in 1989
