St. Mary's Episcopal Church (East Providence, Rhode Island)

St. Mary's Episcopal Church is a historic church in East Providence, Rhode Island.

The congregation traces its history to a Bible school formed in 1867. It was admitted into union with the Episcopal Diocese of Rhode Island in 1871, and became an independent parish in 1894. In 1878, St. Mary's Orphanage, now known as St. Mary's Home was opened; it remains in operation in North Providence.

The Carpenter Gothic church, by George E. Harney, was constructed from 1870 to 1872. It was added to the National Register of Historic Places in 1980.

The church is one of the few buildings remaining of Watchemoket Square, a neighborhood which was once the thriving heart of downtown East Providence.
