The Curoca is an intermittent river in Namibe Province, southern Angola which has residual lagoons in dry seasons.

It is one of only two rivers in Iona National Park, which also includes moving sand dunes of the Namib Desert.

[1][2] The Curoca forms part of the northern border of the park and also runs through the Lagoa dos Arcos and the Regional Natural Park of Namibe (Parque Natural Regional do Namibe).

The lagoons support plants including bamboo and thorn trees and animals such as springbok and oryx.

[3] The seasonal flooding of the river supports the limited agriculture and grazing conducted in the area.
