New Hampden is an unincorporated community in Highland County, Virginia, United States. New Hampden is located in the Blue Grass Valley on VA State Route 640 approximately 5.7 miles (9.2 km) north of Monterey, Virginia. The community is situated on the banks of the South Branch Potomac River west of the northern end of Monterey Mountain and southwest of the community of Blue Grass, Virginia and the Devils Backbone rock outcrop. The community appeared around 1858 and is characterized as having a "regular appearance" in contrast to more haphazardly developed villages. West of New Hampden is the site of a flint quarry used by Native Americans to procure sources of flint for the production of arrowheads. Some accounts state that the area was of such importance that it was considered to be neutral ground by the native tribes.
