The Back River Farm, also known as the Samuel Emerson Farm, is a historic farmstead on Bay View Road in Dover, New Hampshire. The land along the Bellamy River has been farmed since Samuel Emerson acquired 30 acres (12 ha) in the area in 1696, and is the only surviving period farmstead in the area. The farm, including a mid-18th century farmhouse, was listed on the National Register of Historic Places in 1984.
