The Parish of All Saints, Ashmont, is a church of the Episcopal Diocese of Massachusetts located at 209 Ashmont Street in the Dorchester neighborhood of Boston, Massachusetts. Built 1892-1929 for a congregation founded in 1867, it was the first major commission of architect Ralph Adams Cram, a major influence in the development of early 20th-century Gothic church and secular architecture. The church was listed on the National Register of Historic Places in 1980, and is protected by a preservation easement held by Historic New England.
