The Namoi River, a major perennial river that is part of the Barwon catchment of the Murray–Darling basin, is located in the Northern Tablelands and North West Slopes districts of New South Wales, Australia.

The Namoi River rises on the western slopes of the Moonbi Range and Great Dividing Range, near Niangala, at the convergence of the Macdonald River and Boundary Creek, and flows generally west, joined by twenty-seven tributaries, including the Peel, Manilla and Mooki rivers, before reaching its confluence with the Barwon River, near Walgett.

The Namoi River descends 578 metres (1,896 ft) over its 708 kilometres (440 mi) course; passing near the towns of Gunnedah, Boggabri, Narrabri, Wee Waa and Walgett. The flow of the river is impounded by Lake Keepit and Baraneal Lagoon.^[2]
