Tsumeb (; ) is a town of around 35,000 inhabitants and the largest town and the former capital of the Oshikoto region in northern Namibia.

Tsumeb, since its founding in 1905, has been primarily a mining town. The town is the site of a deep mine (the lower workings now closed) whose ore deposits with respect to variety, rarity and aesthetics of minerals have been listed among 100 geological heritage sites around the world by the International Union of Geological Sciences
