Fort Patrick Henry is a small, 872-acre, TVA-managed reservoir located in Sullivan County near Kingsport on the South Fork Holston River in east Tennessee. It extends 10 miles upstream from the dam to Boone Dam; and 8 miles (13 km) above the South Fork Holston River's confluence with the North Fork Holston River (which forms the Holston River proper).

This lake is a run-of-river reservoir, meaning that water is passed through the reservoir without being stored long-term. TVA typically maintains the water level between 1,258 and 1,263 feet of elevation. All of the water that passes through the Watauga, South Holston, and Boone Reservoirs also flows through this small narrow reservoir. Therefore, water moves relatively swiftly through Fort Patrick Henry when compared to other TVA reservoirs and the average hydraulic retention time is only five days.

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.

Fort Patrick Henry is named after the colonial fort, also known as Long Island Station, that was established nearby at the site of present-day Kingsport, Tennessee. The dam was built primarily for hydropower but it is also used to regulate the flow of water downstream to ensure a reliable supply of water for local industry and for cooling water at TVA’s John Sevier Fossil Plant.

Fort Patrick Henry Reservoir is a popular site for fishing, particularly rainbow trout, bluegill, bass, and crappie. Warrior’s Path State Park is located on the reservoir.
