The Prince Regent River is a 106 km long river in the Kimberley region of Western Australia.
The headwaters of the river rise in the Caroline Range near Mount Agnes then flow in a north westerly direction. The river enters and flows through the Prince Regent National Park and past King Cascade and finally discharging into Saint George Basin and Hanover Bay to the Indian Ocean.
The river runs a uniquely straight course following a fault line for the majority of its length.
