Ocoee Dam Number 1 is a hydroelectric dam on the Ocoee River in Polk County in the U.S. state of Tennessee. The dam impounds the 1,930-acre (780 ha) Parksville Reservoir and is the farthest downstream of four dams on the Toccoa/Ocoee River owned and operated by the Tennessee Valley Authority. Completed in 1911, Ocoee No. 1 was one of the first hydroelectric projects in Tennessee.

The Toccoa River and Ocoee River are the names in use for a single 93-mile-long (150 km) river that flows northwestward through the southern Appalachian Mountains of the southeastern United States. It is a tributary of the Hiwassee River, which it joins in Polk County, Tennessee, near the town of Benton. Three power generating dams are operated along it.
