The Bargo River, a watercourse of the Hawkesbury-Nepean catchment, is located in the Southern Highlands and Macarthur districts of New South Wales, Australia.
The Bargo River rises in the southern slopes of Southern Highlands, north of Colo Vale, and flows generally north-east, joined by two minor tributaries, before reaching its confluence with the Nepean River, near Bargo.
In its upper catchment, the river runs through Bargo River State Conservation Area, a nature reserve located between Hill Top and Yerrinbool.[3]
