The Bastyan Power Station is a conventional hydroelectric power station located in Western Tasmania, Australia.

Part of the Pieman River scheme that comprises four hydroelectric power stations, the Bastyan Power Station is the third station in the scheme. The power station is located aboveground at the foot of the rock-filled concrete faced Bastyan Dam which forms Lake Rosebery. Water from the lake is fed to the power station near the centre of the dam wall by a 150-metre (490 ft) single penstock tunnel.

The power station was commissioned in 1983 by the Hydro Electric Corporation (TAS) and the station has one Fuji Francis turbine, with a generating capacity of 81 megawatts (109,000 hp) of electricity. The station output, estimated to be 405 gigawatt-hours (1,460 TJ) annually, is fed to TasNetworks' transmission grid via a 13.8 kV/220 kV Fuji generator transformer to the outdoor switchyard.

The water discharged from the Bastyan Power Station flows into Lake Pieman for use in the Reece Power Station.
