The Ross River is a 49-kilometre waterway in North Queensland that flows through the city of Townsville before emptying into the Coral Sea. It is the major waterway of Townsville and the city's primary source of drinking water. The river rises in the Hervey Range below Pepper Pot Mountain, flows generally north through Lake Ross, across a flat coastal plain, and then east around Mount Stuart into the city, passing through the suburbs of Aitkenvale, Annandale, Condon, Kelso, Mundingburra, Murray, and Rasmussen.

Paddlers should be aware that the river contains crocodiles and turtles, as noted by guided kayaking tours operating on the waterway. The presence of crocodiles is a significant safety consideration for anyone paddling independently. Flow rates along the river are regulated by the Ross River Dam, the largest dam in the catchment, and three weirs exist along the river's course, which will affect route planning and may require portaging. Seven crossings also span the river.

The river connects to Ross Creek and is accessible from The Strand area near Townsville's CBD, which serves as a launch point for paddlers. The mouth of the river, located in South Townsville, is currently being developed into a marina precinct. Commercial kayaking tours operate on the river, offering guided experiences that include wildlife observation.

The river's catchment area covers 1,340 square kilometres. Given its location in tropical North Queensland, paddlers should factor in the region's wet and dry season patterns when planning trips.
