Fort Patrick Henry Dam is a hydroelectric dam on the South Fork Holston River within the city of Kingsport, in Sullivan County in the U.S. state of Tennessee. It is the lowermost of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the early 1950s to take advantage of the hydroelectric potential created by the regulation of river flow with the completion of Watauga Dam, South Holston Dam, and Boone Dam (which were primarily flood control structures) further upstream in preceding years. The dam impounds the 872-acre (353 ha) Fort Patrick Henry Lake. While originally built for hydroelectric generation, the dam now plays an important role in the regulation of water flow and water temperature for the John Sevier Fossil Plant and other industrial plants downstream.
Fort Patrick Henry Dam is named for a Revolutionary War-era fort once located at nearby Long Island of the Holston.
Fort Patrick Henry Dam is located 8 miles (13 km) above the South Fork Holston River's confluence with the North Fork Holston River (which forms the Holston River proper). The city center of Kingsport is just northwest of the dam, and the unincorporated community of Colonial Heights is also nearby. Warriors' Path State Park occupies part of Fort Patrick Henry Lake's shoreline. Fort Patrick Henry Dam is 44 miles (71 km) upstream from the retention dam at John Sevier Fossil Plant and about 98 miles (158 km) upstream from Cherokee Dam, both of which are on the Holston River proper.
