The Mau Mau Uprising, also known as the Mau Mau Rebellion, Mau Mau Revolt, or Kenya Emergency, was a military conflict that took place in British Kenya between 1952 and 1960. It involved Kikuyu-dominated groups summarily called Mau Mau, the white settlers, and elements of the British Army including local Kenya Regiment mostly consisting of the British, auxiliaries, and anti-Mau Mau Kikuyu. The capture of rebel leader Dedan Kimathi on 21 October 1956 signalled the ultimate defeat of Mau Mau, and essentially ended the British military campaign.

The Mau Mau failed to capture widespread public support, partly due to the British policy of divide and rule, and the movement remained internally divided, despite attempts to unify its various strands. The British, meanwhile, could draw upon their ongoing efforts to put down another rebellion in Malaya.

The uprising created a rift between the European colonial community in Kenya and the metropole, but also resulted in violent divisions within the Kikuyu community. The financial cost of the uprising to the former colony amounted to £55 million.
