The Beaufort River is a river in the South West of Western Australia.
The rivers has its headwaters west of Woodanilling near Melbourne Vale and flows in a westerly direction until it flows into the Arthur River near Duranillin. The Arthur river is a tributary of the Blackwood river.
The only tributary of the river is the 7.5 kilometres (5 mi) Beaufort River East that joins the main river just East of where it crosses Albany Highway.
The river was named by John Septimus Roe, the Surveyor General of Western Australia, in 1835 after his friend Rear Admiral Sir Francis Beaufort who was a hydrographer in the British Admiralty.
The river's catchment falls within the Blackwood catchment's Beaufort zone as part of the Beaufort system. The system is composed of broad valley floors with a grey sandy duplex and was previously a wandoo sheoak [4] woodland but has now mostly been cleared for agriculture.
