Fort Washington, located near the community of Fort Washington, Maryland, USA, was for many decades the only defensive fort protecting Washington D.C. The original fort, overlooking the Potomac River, was completed in 1809, and was named Fort Warburton. During the War of 1812, the fort was destroyed by its own garrison during a British advance. The current historic fort — maintained by the National Park Service — was initially constructed in 1824. It is a stone structure with a good cannon shot down the Potomac River. The fort was extensively remodeled in the 1840s and 1890s. The Fort was turned over to the U.S. Department of the Interior in 1946 after its last military personnel departed.

The expansive grounds of the present Fort Washington Park, with its extensive hiking/bicycle paths and river view, are a scenic venue for picnicking, fishing, and outdoor recreation. Historical re-enactments are held periodically at the Fort, and there is a small museum. In 2006, repairs were done to shore up the crumbling outer wall, in preparation for the 200th anniversary.

The Fort Washington Light, located below the fort, was established in 1857. The current tower, standing 28 feet tall, was constructed in 1882.
