South Canaan Congregational Church is a historic Congregational church building at CT 63 and Barnes Road in the town of Canaan, Connecticut. It was built in 1804 and added to the National Register of Historic Places in 1983. The South Canaan Church is one of three Connecticut churches modeled after a church in Pittsfield, Massachusetts, that was built in 1793 according to a design by Charles Bulfinch. As such, it is a representative of the first generation of architecturally stylish church buildings, built between 1790 and 1810, that were replaced the earlier plain-style meetinghouses.
