Campbells River, a perennial stream that is part of the Upper Macquarie catchment within the Murray–Darling basin, is located in the central–western region of New South Wales, Australia. The river rises on the western slopes of the Great Dividing Range about 6.4 km south of Black Springs. It flows generally north by west towards its confluence with the Fish River 9 km south–south–east of Bathurst to become the Macquarie River; descending 473 m over its 82 km course. The river is impounded by Ben Chifley Dam upstream of Bathurst and carries water released from the dam for Bathurst's potable water supply.
