The Unitarian Church (also known as the First Congregational Society - Unitarian of Hampton Falls) is a historic American church on Exeter Road (New Hampshire Route 88) in Hampton Falls, New Hampshire. Built in 1838, it is a rare example of an Greek Revival temple front in the state, and is distinguished by the presence of Victorian trompe-l'œil panels and ribbing on its interior walls. The church was listed on the National Register of Historic Places in 1984. It is presently used for services in the summertime.
