Mallows Bay is a small bay on the Maryland side of the Potomac River in Charles County, Maryland, and located at Coordinates: . The bay is the location of what is regarded as the "largest shipwreck fleet in the Western Hemisphere" and is described as a "ship graveyard."
Charles County operates Mallows Bay Park (1440 Wilson Landing Road in Nanjemoy, Maryland). This small park contains the graves of more than 230 ships sunk in the river. Almost ninety were poorly constructed steamships built during World War I; in 1925 they were burned and scuttled in the bay. Bethlehem Steel then built a salvage basin during World War II to recover metal from the abandoned ships. The ships form a reef that hosts an array of wildlife. A 0.8-mile trail loops around Mallows Bay Park and the salvage basin.
