Évariste Leon Kimba Mutombo (16 July 1926 – 2 June 1966), better known as Évariste Kimba, was a Congolese journalist and politician who served as Foreign Minister of the State of Katanga from 1960 to 1963 and Prime Minister of the Democratic Republic of the Congo from 13 October to 25 November 1965.
Kimba was born in 1926 in the Katanga Province, Belgian Congo. Following the completion of his studies he worked as a journalist and became editor-in-chief of the Essor du Congo. In 1958, he and a group of Katangese concerned about domination of their province by people from the neighbouring Kasaï region founded the Confederation of Tribal Associations of Katanga (CONAKAT), a regionalist political party. On 30 June 1960, the Congo became independent and shortly thereafter Moise Tshombe declared the secession of the Katanga Province. Kimba played an active role in the separatist state's government as its Minister of Foreign Affairs and participated in numerous talks with the central government aimed at political reconciliation. Following the collapse of the secessionist state in early 1963, Kimba had a falling-out with Tshombe and took up several ministerial posts in the new province of South Katanga.
