Nathaniel Mountain Wildlife Management Area is located on 10,675 acres (43.20 km2) south of Romney in Hampshire County, West Virginia.

The WMA was expanded in November 2003 after the WVDNR purchased 1,800 acres (7.3 km2) from the MeadWestvaco Corporation.

The WMA's forests are primarily dominated by mature species of oak, hickory, and Virginia pine.

White-tailed deer, turkey, grouse, squirrel, and black bears are available for hunting.

Mill Run, a steep mountain stream that meanders through a seven-mile (11 km) course to join the South Branch Potomac River, is also located in the Nathaniel Mountain WMA.
