The Condamine River, part of the Balonne catchment that is part of the Murray-Darling Basin, drains the northern portion of the Darling Downs, an area of sub-coastal southern Queensland, Australia. The river is approximately 500 kilometres (310 mi) long and rises on Mount Superbus, South East Queensland's highest peak, on the western slopes of the Great Dividing Range, approximately 100 kilometres (62 mi) from the east coast of Queensland, and then flows north west across the Darling Downs, then west. The Condamine River is a tributary of the Darling River.

The Balonne River, part of the Murray-Darling Basin system, is a short yet significant part of the inland river group of South West Queensland, Australia.
