The Horton River, a perennial stream[1] of the Barwon catchment within the Murray–Darling basin, is located in the Northern Tablelands and North West Slopes districts of New South Wales, Australia.

The river rises on the northern slopes of the Nandewar Range, below Mount Kaputar, and flows generally southeast and north, joined by six tributaries before reaching its confluence with the Gwydir River, north west of Bingara; descending 1,060 metres (3,480 ft) over its 134 kilometres (83 mi) course.

[2] The valley of the Horton River is used for grazing and some cropping.

Other nearby towns, outside the valley, are Barraba, Bingara, and Narrabri.
