Western River is a locality in the Australian state of South Australia located on the north coast of Kangaroo Island overlooking Investigator Strait about 170 kilometres (110 miles) south-west of the state capital of Adelaide and about 64 kilometres (40 miles) west of the municipal seat of Kingscote.

[2][8][9] Western River occupies land bounded by Investigator Strait to the north.

Land use is divided between conservation and agriculture with the former applying to the coastline in order to “enhance and conserve the natural features of the coast” and to the protected area known as the Western River Wilderness Protection Area while the latter applies to land in the locality's southern half.
