The Henniker Town Hall is the town hall of Henniker, New Hampshire. The wood frame building, built in 1786-87, is one of a small number of surviving 18th century meetinghouses in New Hampshire. At that time, its main entrance was on the long south wall, facing the raised pulpit on the north wall, and the floor was taken up by pews. The interior was decorated with high quality woodwork, which still survives. The roughly rectangular building had 1.5 story enclosed porch extensions on both sides. The building was listed on the National Register of Historic Places in 1981.
