Bighorn Lake is a reservoir behind Yellowtail Dam within the Bighorn Canyon National Recreation Area, located in southern Montana and northern Wyoming.
The reservoir is 40 mi (64 km) south of Billings, Montana. It stretches the entire 72 mi (115 km) length of the Bighorn Canyon at full pool.
Bighorn Lake was created by the 1965 construction of Yellowtail Dam on the Bighorn River, near Fort Smith, Montana.
