The
Potomac Highlands of West Virginia (or
Potomac Highlands) centers on five counties (Grant, Hampshire, Hardy, Mineral, and Pendleton) in the upper
Potomac River watershed in the western portion of the state's
Eastern Panhandle, bordering
Maryland and
Virginia. Because of geographical proximity, similar topography and landscapes, and shared culture and history, the Potomac Highlands region also includes Pocahontas, Randolph, and Tucker counties, even though they are in the
Monongahela River or
New River watersheds and not that of the
Potomac River.
