Hanging Rock is an unincorporated community in Hampshire County in the U.S. state of West Virginia. Hanging Rock is named for the "Hanging Rock" outcrop that hangs over the Northwestern Turnpike (U.S. Route 50). It should not be confused with the plural "Hanging Rocks" over the South Branch Potomac River north of Romney at Wapocomo. Originally, the community of Hanging Rock sprang up in the Henderson Hollow gap of North River Mountain. While only a few buildings of the old hamlet remain, today's Hanging Rock is situated at the intersection of North River Road (County Route 50/21) and Delray Road (West Virginia Route 29) where the North River flows under U.S. Route 50 towards the Cacapon.
