The Cooks Vale Creek, a mostly–perennial river[2] that is part of the Lachlan sub-catchment of the Murrumbidgee catchment within the Murray–Darling basin, is located in the South West Slopes region of New South Wales, Australia.

Formed by the confluence of two unnamed watercourses, the Cooks Vale Creek (technically a river[2]) rises southwest of Hadley, on the south western slopes of the Great Dividing Range, and flows generally northwest by north before reaching its confluence with the Abercrombie River east of Tuena.
