Ocoee Dam Number 2 is a hydroelectric dam on the Ocoee River in Polk County in the U.S. state of Tennessee. The dam impounds the Ocoee No. 2 Reservoir and is one of four dams on the Toccoa/Ocoee River owned and operated by the Tennessee Valley Authority. Ocoee Dam No. 2— which was completed in 1913— is perhaps most notable for its design, which utilizes a wooden flume that carries water from the reservoir down the side of the Ocoee Gorge to the dam's powerhouse 5 miles (8.0 km) downstream. Ocoee No. 2 is also situated at the center of one of the nation's top whitewater rafting locations, and the dam's releases help to maintain consistent rapids on the river during warmer months.

Ocoee Dam No. 2 is located 24 miles (39 km) above the mouth of the Ocoee River, near the center of the Ocoee Gorge, a steep-sided valley sliced as the Ocoee winds its way westward through the Appalachian Mountains. Ocoee No. 2 is 12 miles (19 km) upstream from Ocoee Dam No. 1 and 5 miles (8.0 km) downstream from Ocoee Dam No. 3. The flume connecting Ocoee Dam No. 2 to its powerhouse winds its way along the cliffs overlooking the south side of the gorge before dropping the water to the powerhouse 5 miles (8.0 km) downstream from the dam. The dam and reservoir are surrounded by the Cherokee National Forest, and the only major road access is provided via the Ocoee Scenic Byway, a section of U.S. Route 64.

Ocoee Dam No. 2 is a rock-filled crib-type dam 30 feet (9.1 m) high and 450 feet (140 m) long. The two units at the powerhouse downstream from the dam have a generating capacity of 23,100 kilowatts. The dam typically schedules major recreational releases on weekends in spring and fall and five days per week in summer months.

The dam's flume consists of a wooden trough situated upon a shelf carved out of the cliffside. The trough carries the water to a point just above the powerhouse where it drops the water 250 feet (76 m) through two large steel pipes to the powerhouse below. Without this flume system, the dam (at just 30 feet high) would be practically useless as a power plant.
