Lake Sharpe is a large reservoir behind Big Bend Dam on the Missouri River in central South Dakota, USA. The lake has an area of 56,884 acres (230.20 km²) and a maximum depth of 78 ft (24 m). Lake Sharpe is approximately 80 mi (130 km) long, with a shoreline of 200 mi (320 km).

Construction of Big Bend Dam began in 1959, and Lake Sharpe was named for Merrill Q. Sharpe, the 17th Governor of South Dakota.

Species of fish in the reservoir include walleye, sauger, smallmouth bass, channel catfish, and white bass. Walleye are the primary gamefish in the lake, and gizzard shad are the main food source for the walleye.

The South Dakota Department of Game, Fish and Parks maintains several recreation areas and boat launching facilities around the lake. West Bend Recreation Area and Farm Island State Recreation Area are both located on the lake.

Much of the western shore of the lake is within the Lower Brule Indian Reservation, while the Crow Creek Indian Reservation lies along the eastern shore.
