Fort Foote was an American Civil War-era wood and earthwork fort that composed a portion of the wartime defenses of Washington, D.C., by helping defend the Potomac River approach to the city. It operated from 1863 to 1878, when the post was abandoned, and was used only briefly during the First and Second World Wars. Today, the fort is operated as Fort Foote Park, which is maintained by the U.S. National Park Service as part of the National Capital Parks-East system. The area's mailing address is Fort Washington, MD.

Today, the area that once held the fort is largely forested, though some of the original bastions have been preserved. Two 15-inch (381 mm) guns sit on carriages overlooking the Potomac. Only one was originally used at Fort Foote. The other is from Battery Rodgers, which lay on the opposite side of the river during the Civil War.
