The York Haven Dam is a low head, run-of-the river, dam and hydroelectric plant that is located on the Susquehanna River in the United States.

This dam is situated 12 miles (19 km) south of Harrisburg, Pennsylvania, at the Conewago Falls impounding about 8,000 feet (2,400 m) of the river to the west side of Three Mile Island, where the river drops 19 feet (5.8 m) in 14 mile (0.40 km). When the dam was completed in 1904, it was the third largest in the world.[1]
