Little Hunting Creek is a 3.6-mile-long (5.8 km) primarily tidal tributary of the Potomac River located in Fairfax County, Virginia, not to be confused with Hunting Creek farther north. A stone-arch bridge, completed in 1931, carries traffic from the George Washington Memorial Parkway across the narrow mouth of the creek, located 83.9 nautical miles (155.4 km) upriver from the mouth of the Potomac. The creek marks the location along the Potomac River where the Washington family built their Mount Vernon plantation during colonial times.
