The Wouri is a river in Cameroon. Cameroon has many water bodies and amongst these are two major rivers, the Sanaga, the longest at about 525 km long and the Wouri, the largest. The Wouri forms at the confluence of the rivers Nkam and Makombé, 32 km (20 mi) northeast of the city of Yabassi. It then flows about 160 km (99 mi) southeast to the Wouri estuary at Douala, the chief port and industrial city in the southwestern part of Cameroon on the Gulf of Guinea. The river is navigable about 64 km (40 mi) upriver from Douala.
