Joseph Cimpaye (1929 – c.May 1972) was a Burundian politician and writer. Born into an educated family from the Hutu ethnic group, Cimpaye was considered one of Burundi's leading intellectuals in the late colonial period. He became involved in politics under Belgian colonial rule, co-founding the Union of Popular Parties (Union des parties populaires, UPP), a cartel which was opposed by the more popular anti-colonial Union for National Progress (Union pour le Progrès national, UPRONA). Cimpaye briefly held the position of prime minister in 1961 before UPRONA was decisively returned in the country's first elections ahead of Burundi's independence in July 1962. Although retiring from politics, he was later arrested under the regime of Michel Micombero in 1969.
