Guntersville Dam is a hydroelectric dam on the Tennessee River in Marshall County, Alabama. It is one of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to create a continuous navigation channel on the entire length of the river and bring flood control and economic development to the region. The dam impounds the Guntersville Lake of 67,900 acres (27,500 ha), and its tailwaters feed into Wheeler Lake.

Guntersville Dam is named for the city of Guntersville, Alabama, which is located about 10 miles (16 km) upstream. The city is named for its first settler, John Gunter (d. 1836), who arrived in the late 18th century.
