Styx River, a perennial stream of the Macleay River catchment, is located in the Northern Tablelands district of New South Wales, Australia.

Course and features

The Styx River starts below Point Lookout in the Great Dividing Range along the eastern escarpment of the Northern Tablelands, south southeast of Ebor, and flows generally southwest, joined by two minor tributaries before reaching its confluence with the Chandler River, south southwest of Jeogla. The river descends 1120 m over its 60 km course; rapidly descending into a deep gorge where it meets the Chandler River.
