Abercrombie River, a perennial river that is part of
the Murray–Darling basin, is located in the central
west of New South Wales, Australia.

The Abercrombie River rises to the east of the
village of Mount Werong and generally flows
westward towards its confluence with the Lachlan
River at Wyangala Dam near Cowra. The river
flows through freehold land as well as the
Abercrombie River National Park, and provides
habitat for platypus and rakali, dropping 758
metres (2,487 ft) over its course of 130 kilometres
(81 mi).

The Abercrombie River is the furthest east of the
inland flowing rivers.
