The Cuyuní River is a South American river and a tributary of the Essequibo River. It rises in the Guiana Highlands of Venezuela, where it descends northward to El Dorado, and turns eastward to meander through the tropical rain forests of the Cuyuni-Mazaruni Region of Guyana. It finally turns southeastward, flowing to its confluence with the Mazaruni River.
The Cuyuní River marks a border in the Guyana–Venezuela territorial dispute for approximately 100 kilometres (62 mi).
Makarapan Mountain is a sandstone range by the Cuyuní.
