Boyup Brook is a town in the south-west of Western Australia, 269 kilometres (167 mi) south-southeast of Perth and 31 kilometres (19 mi) northeast of Bridgetown. The name Boyup is derived from the name of a nearby pool "Booyup", an Aboriginal term meaning "place of big stones" (large granite outcrops common in the area) or "place of big smoke" (from burning the many surrounding grass trees). The town's economy is primarily agricultural. It is a Cooperative Bulk Handling receival site.
