Cambridge is a township in Coös County in the state of New Hampshire. The population was 16 at the 2020 census,[2] up from 8 at the 2010 census.[3]

In New Hampshire, locations, grants, townships (which are different from towns), and purchases are unincorporated portions of a county which are not part of any town and have limited self-government (if any, as many are uninhabited). Cambridge is part of the Berlin, NH–VT Micropolitan Statistical Area.


It was granted in 1793 to Nathaniel Rogers and others and contained about 23,160 acres (9,370 ha).[4]


Most of the township is forested wilderness, but it contains the southernmost edge of Umbagog Lake, accessed via New Hampshire Route 26 from Errol or from Upton, Maine. The lake's outlet, 6 miles (10 km) to the north in Errol, is the source of the Androscoggin River, which flows southward through the northwest part of Cambridge. A portion of the 13-Mile Woods Scenic Area follows the Androscoggin through the township, as does New Hampshire Route 16, which leads north to Errol and south to Berlin.

According to the United States Census Bureau, the township has a total area of 51.7 square miles (133.9 km2), of which 51.0 square miles (132.1 km2) are land and 0.73 square miles (1.9 km2), or 1.41%, are water.[1] The entire township is part of the Androscoggin River watershed, with its three main tributaries in the township being, from north to south, Mollidgewock Brook, Bog Brook, and Chickwolnepy Stream (along with its own tributary, Blackstrap Brook). The highest point in the township is the summit of Cambridge Black Mountain, at 2,780 feet (850 m) above sea level. The township is bordered to the east by Oxford County, Maine.
