The O'Connell River is a river in North Queensland, Australia.
The headwaters of the river rise in a valley under Mount Millar in the Clarke Range, part of the Great Dividing Range, just north of the Eungella National Park. It flows in a northerly direction parallel with the Bruce Highway passing Kamo and Caping then discharging into the Repulse Fish Habitat area near Covering Beach and onto the Coral Sea.
The river has a catchment area of 2388km2 of which an area of 128km2 is composed of estuarine wetlands.[5]
