Gairdner River is a river located in the Great Southern region of Western Australia. There is another Gairdner river in Western Australia, located in the Kimberley region.

The river originates at Lake Magenta on the Yilgarn plateau about 300 metres (984 ft) sea level, then flows in a South Easterly direction through the Fitzgerald River National Park until it terminates in the Gordon Inlet.

About 60% of the catchment has been cleared for pastoral and grazing land and as a result the water quality has become saline. Salinity levels vary from 3 after rains when the river is flowing to 50 during the summer time.

The river was named after Gordon Gairdner of the colonial office by John Septimus Roe in 1848[2]
