The Gordon Dam, also known as the Gordon River Dam, is a major gated double curvature concrete arch dam with a controlled spillway across the Gordon River, located in Southwest National Park, Tasmania, Australia. The impounded reservoir is called Lake Gordon.

The dam was constructed in 1974 by the Hydro Electric Corporation (TAS) for the purpose of generating hydro-electric power via the conventional Gordon Power Station located below the dam wall.[1][2]
