The Coeroeni River is a river in South America. It arises in the northwestern part of Pará, Brazil, and flows northward remaining in Brazil for only a few kilometres. The Coeroeni goes on to form the border of the disputed Tigri Area by Guyana and Suriname. It eventually flows into the Courantyne River, which forms the international boundary between Guyana–Suriname.
