The Paroo River, a series of waterholes, connected in wet weather as a running stream of the Darling catchment within the Murray–Darling basin, is located in the South West region of Queensland and Far West region of New South Wales, Australia.

Paroo is the local Aboriginal word for the bony bream fish, which are common in the river.

The river is joined by forty-three minor tributaries; as it descends 242 metres (794 ft) over its 1,210-kilometre (750 mi) course.
