Collie is a town in the South West region of Western Australia, 213 kilometres (132 mi) south of the state capital, Perth, and 59 kilometres (37 mi) inland from the regional city and port of Bunbury.

It is near the junction of the Collie and Harris Rivers, in the middle of dense jarrah forest and the only coalfields in Western Australia.

To its west is the Wellington Dam, a popular location for fishing, swimming and boating.
