The Unitarian Meetinghouse is a historic church at the junction of Connecticut Routes 169 and 6 in the village center of Brooklyn, Connecticut. Built in 1771, it is one of a small number of pre-Revolutionary church buildings in the state, and distinctive for having a sufficiently complete documentary record to support a complete restoration. It retains a configuration distinctive of that period, with its main entrance on the long side of the building, and the pulpit opposite. The bell tower with steeple is located at one of the short ends, suggestive of the 19th century change to place the entrance there as well. The building was listed on the National Register of Historic Places in 1972.
