Wituland (also Witu, Vitu, Witu Protectorate or Swahililand) was an approximately 3,000 square kilometres (1,200 sq mi) territory in East Africa centered on the town of Witu just inland from Indian Ocean port of Lamu north of the mouth of the Tana River in what is now Kenya.

Founded in 1858 by the former ruler of the insular Pate sultanate after several abortive moves to the mainland, the native sultanate of Wituland was a haven for slaves fleeing the Zanzibar slave trade and thus a target of attacks from the Sultanate of Zanzibar (ruled by a branch of the Omani dynasty, under British protectorate). Facing an increase in slaving raids from the Sultanate of Zanzibar, the Sultan of Witu formally requested German protection so that he "finally has relief from the attacks of Zanzibar warriors."

In 1885, the German brothers Clemens and Gustav Denhardt negotiated a treaty with Ahmed ibn Fumo Bakari, the first mfalme (Swahili for sultan or king) of Witu who ceded, on 8 April 1885, 25 square miles of territory to the brothers' "Tana Company", and the remainder of the Wituland became the German Protectorate of Wituland (Deutsch-Witu) on 27 May 1885. The Reich was represented there by the German Residents: Gustav Denhardt (1856–1917; in office 8 April 1885 – 1 July 1890) and his deputy Clemens Andreas Denhardt (1852–1928). German rule was relatively mild, and the territory continued being a haven for escaped slaves.
