The Longa is a river in central Angola. The river forms the southern border of Kissama National Park and the border of Bengo Province and Cuanza Sul Province. Its mouth is protected by a long sand spit at the Atlantic Ocean. It has two major tributaries, Nhia and Mugige.[1] The floodplain in the lower reaches of the river includes Lake Hengue and Lake Toto.
An eco-tourist fishing lodge is at the mouth of the river.[2] A mercenary base was located on the Longa River during the Angola Civil War.[3]
The Chiloglanis sardinhai (a catfish) is known only from the Longa and Caimbambo Rivers.[4]
