奥卡万戈河（英语：Okavango River），上游河段又名库邦戈河（Cubango River），是南部非洲的一条内陆河，也是非洲南部第四长河。它发源于安哥拉中部的比耶高原，沿着安哥拉和纳米比亚的国界，由西北向东南流入博茨瓦纳，形成面积达16,835km的奥卡万戈三角洲。南部有支流汇入恩加米湖，再通过季节性的博泰蒂河（Botletli River）继续东流，最后消失在马卡迪卡迪盐沼。

河流全长1600km，流域面积80万km，河口流量250m/s。主要支流有奎托河、库希河等。

The Okavango River is a river in southwest Africa. It is the fourth-longest river system in southern Africa, running southeastward for 1,600 km (990 mi). It begins in Angola, where it is known as the Cubango River. Further south it forms part of the border between Angola and Namibia, and then flows into Botswana, draining into the Moremi Game Reserve.
