The South Parish Congregational Church and Parish House is a historic church at 9 Church Street in Augusta, Maine. Built in 1865, the church is a major Gothic Revival work of Maine's leading mid-19th century architect, Francis H. Fassett, and its 1889 parish house, designed by James H. Cochrane, is a rare example in the state of Stick style architecture. The property was listed on the National Register of Historic Places in 1980. The congregation was established in 1773, when the area was part of Hallowell.
