Newell Falls is a tiered, multi-step waterfall located along the Waterfall Way in the Dorrigo Mountains of New South Wales, within or adjacent to Dorrigo National Park.

Formed by an unnamed tributary of the Rosewood River, the falls drop approximately 30 metres down the rockface beside the road before passing under the highway through a culvert.

The falls are named after Hugh Newell, who served as New South Wales Commissioner for Main Roads from 1932 until his death in 1941.

The waterfall flows year-round but is most impressive following rainfall, and during periods of heavy sustained rain it can spill across the road, occasionally causing temporary closures.

A small parking area off Waterfall Way allows visitors to stop and view the falls, with only a short walk of around 50 metres required. It is one of several roadside waterfalls encountered on the scenic drive between Bellingen and Dorrigo.
