The Canaan Street Historic District encompasses the historic original town center of Canaan, New Hampshire. It is a basically linear district, running along Canaan Street roughly from Prospect Hill Road in the north to Moss Flower Lane in the south. The town flourished first as a stagecoach stop, and then as a resort colony in the late 19th century. The historic district was listed on the National Register of Historic Places in 1973. It included 60 contributing buildings.
