The First Baptist Church is a historic American Baptist church at Magazine and River Street in Cambridge, Massachusetts within Central Square. In 1817 the church congregation was founded in the home of James Hovey. In 1844 several members of First Baptist Church left to found nearby Old Cambridge Baptist Church. First Baptist Church's current Gothic building was constructed in 1881 to a design by Hartwell and Richardson. It was added to the National Register of Historic Places in 1975.
