The Nyong (formerly German: Yong) is a river in Cameroon. The river flows approximately 690 kilometres (430 mi) to empty into the Gulf of Guinea.

Course

The Nyong originates 40 km (25 mi) east of the town of Abong-Mbang, where the northern rain forest feeds it.^[2] The river's length is almost parallel to the lower reaches of the Sanaga River. Its mouth is in Petit Batanga, 60 km (40 mi) south-southwest of Edéa.^[3] In two places, Mbalmayo and Déhané, the river has huge rapids. The first 400 km (250 mi) of the river, between Abong-Mbang and Mbalmayo, are navigable for small boats from April to November.
