The Coen River is situated in the Cape York Peninsula in Queensland, Australia.
The present (1996) Pennefather River (renamed 1894) was originally called the Coen river by Jan Carstenszoon in honour of Jan Pieterszoon Coen, Governor-General of the Dutch East Indies. The present Archer River was probably confused by Matthew Flinders with Carstenszoon's Coen River. The Coen River is a tributary of the Archer river and was for a time known as the South Coen River.
