The All Souls Church, also known as the First Unitarian Universalist Church, is a historic church at 196 Elm Street in Braintree, Massachusetts. It is a large fieldstone structure, in a cruciform plan with a square tower that has a crenellated top. The gable ends are decorated with bargeboard, and the entrance is set under a gabled entry porch below a large window with Gothic tracery. The church was designed by Boston architect Edwin Lewis and built in 1905 for a congregation organized in 1900; it is Braintree's first stone church building. Land for the building was donated by George O. Wales, a leading force in uniting Braintree's Unitarian and Universalist congregations. (The larger national church organizations did not formally merge until 1961.)
