Benue (bānwā´), river, W Africa, chief tributary of the Niger. It flows c.880 mi (1,416 km) W from Cameroon into the Niger River at Lokoja, Nigeria. The Benue, which carries much commercial traffic, is almost entirely navigable by power-driven boats in August and September, the height of the rainy season. Large mineral deposits (tin, marble, limestone, gold) are exploited in the river valley.
