South Parish (also known as South Church or South Unitarian Universalist Church) is a church at 292 State Street in Portsmouth, New Hampshire, in the United States. The granite church building was built in 1824-26, and was at the time one of the first large-scale granite buildings in northern New England. It is built of granite quarried in Rockport, Massachusetts, and features a classical pedimented portico supported by Tuscan columns. The building was listed on the National Register of Historic Places in 1979.
