Island Bend Dam is a major gated concrete gravity dam with a controlled spillway across the Snowy River in the Snowy Mountains region of New South Wales, Australia.

The dam's main purpose is for the diversion of water for generation of hydro-power and is one of the sixteen major dams that comprise 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.

At 100% capacity the dam wall holds back 3,084 megalitres (108.9×10^6 cu ft) of water.

The controlled spillway is capable of discharging 2,832 cubic metres per second (100,000 cu ft/s).

The combined water is then sent West through the Snowy-Geehi trans-mountain tunnel to Geehi Dam for generation in the Murray Power Stations.
