The Kent River is a river in Western Australia’s Great Southern region.
The river’s headwaters are rising near Tenterden. It lows in a south-western direction, crosses the Muirs Highway east of Rocky Gully, flows through Mount Roe-Mount Lindesay National Park, crosses the South Coast Highway near Kenton, flows through the swampland of the Owingup Nature Reserve, and eventually discharges into Irwin Inlet’s eastern side.
