Truro Town Hall, formerly Union Hall, is the town hall of Truro, Massachusetts. It is located on Town Hall Road, east of Massachusetts Route 6. The two story wood-frame building was built in 1848 to serve as a meeting place for several fraternal organizations, including the International Order of Odd Fellows and the Sons of Temperance. It served these organizations for only a few years, and was rented by the town for town meetings for a time before being purchased by the town. The building exhibits Greek Revival features, including corner pilasters and a deep architrave. The roof is topped by an octagonal cupola mounted on a square structure.
