The Superior Dam is a hydroelectric barrage dam crossing the Huron River. It is located in Superior Township in Washtenaw County in the U.S. state of Michigan. It was completed in 1920 and currently provides hydroelectricity to the nearby city of Ann Arbor, which owns and maintains the dam and power station.

The Huron River is a 130-mile-long (210 km) river in southeastern Michigan, rising out of the Huron Swamp in Springfield Township in northern Oakland County and flowing into Lake Erie, as it forms the boundary between present-day Wayne and Monroe counties. Thirteen parks, game areas, and recreation areas are associated with the river, which passes through the cities of Dexter, Ann Arbor, Ypsilanti, Belleville, Flat Rock and Rockwood that were developed along its banks.
