Bell River, a watercourse that is part of the Macquarie catchment within the Murray–Darling basin, is located in the central west region of New South Wales, Australia.

The river rises in the hills north-west of Orange and flows generally north past the town of Molong, joining the Macquarie River at Wellington.

[3] Platypus have often been sighted in the lower reaches of the Bell River.

[4] The original inhabitants of the land surrounding the Bell River were Australian Aborigines of the Wiradjuri clan.

[2] Alluvial gold was discovered in and along the river in 1851, inspiring a minor gold rush, most notably near the confluence of the Nubrigyn Creek with the Bell River.
