The Essequibo River (Spanish: Río Esequibo originally called by Alonso de Ojeda Río Dulce) is the largest river in Guyana, and the largest river between the Orinoco and Amazon.
Rising in the Acarai Mountains near the Brazil–Guyana border, the Essequibo flows to the north for 1,014 kilometres (630 mi) through forest and savanna into the Atlantic Ocean. With a total drainage basin of 151,000 square kilometres (58,000 sq mi) and an average discharge of 4,531 cubic metres per second (160,000 cu ft/s).
Territory near the river is argued over by Venezuela and Guyana.
