The Canaan Chapel (also known as Canaan Free Will Baptist Church) is a historic chapel on Canaan Road in Barrington, New Hampshire. The single story wood frame building was built in 1881, and is one of a small number of surviving area Free Will Baptist churches of the period. The interior of the building consists of a vestibule, with a small room off to the right, and an auditorium space measuring about 24' by 32'. There is a raised stage at the far end, at whose center stands a raised pulpit. An 1890 organ manufactured by the Boston Organ Company occupies the corner to the left of the pulpit. The property includes a c. 1898 horse shed.
