Mammoth Pool Reservoir is a reservoir on the San Joaquin River in the Sierra Nevada, within the Sierra National Forest in California. It creates the border between Fresno County and Madera County. It is about 45 miles (72 km) north-northeast of Fresno.

The 123,000 acre⋅ft (152,000,000 m3) reservoir is formed by Mammoth Pool Dam, an earth-fill dam completed in 1960. It was built by Southern California Edison for hydroelectricity production. The dam's power plant can produce up to 190 megawatts. The dam, reservoir and power plant are part of the Big Creek Hydroelectric Project, perhaps the most extensive hydroelectric system in the world.
