The 300 km long Jamunda river originates in the plateau Serra do Jatapu near the division of the northern Brazilian States of Roraima, Amazonas and Pará, from there it flows down, forming the natural division between Amazonas and Pará, crossing the Nhamunda-Mapuera national ecological reservation (EG033) before joining the Amazon River near the small village of Nhamundá.

The river, which flows through the Lago Nhamundá, is a medium size left-hand affluent of the Amazon River.
