Tantangara Dam is a major ungated concrete gravity dam with concrete chute spillway across the Murrumbidgee River in Tantangara, upstream of Adaminaby in the Snowy Mountains region of New South Wales, Australia. The dam is part of the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. The purpose of the dam includes water management and conservation, with much of the impounded headwaters diverted to Lake Eucumbene. The impounded reservoir is called Tantangara Reservoir.
