Benger is a locality just north of Brunswick Junction in the South West of Western Australia.

It is also a crossing loop on the south-west railway between Armadale and Bunbury.

Before European settlement, the region was inhabited by the Pindjarup people, in whose language "Benger" may have meant "swamp" according to some sources (the word Pijar was also used).

[2] The explorers Thomas Peel and Stephen Henty travelled through the district in 1835.

[3][4] A bushfire broke out in the Benger swamp near the town in January 2013, burning out 300 hectares (741 acres) of farmland.
