The People's Republic of the Congo (French: République populaire du Congo) was a Marxist–Leninist socialist state that existed in the Republic of the Congo from 1969 to 1992.

The People's Republic of the Congo was founded in December 1969 as the first Marxist-Leninist state in Africa, three months after the government of Alphonse Massamba-Débat was overthrown in the September 1968 coup d'état. The ruling Congolese Party of Labour (French: Parti congolais du travail, PCT) appointed Marien Ngouabi as president, who established the Congo as a one-party communist government aligned with the Soviet Union. Ngouabi was assassinated in 1977 and succeeded by Joachim Yhombi-Opango until he was overthrown in 1979. Denis Sassou Nguesso succeeded Yhombi-Opango, confirmed the PCT's rule in the Congo with a new constitution, formed closer relations with France, and allowed greater foreign investment in the country. The People's Republic of the Congo transitioned into a multi-party following the dissolution of the Soviet Union in 1991, restoring the country's earlier name and flag, and ceased to exist by March 1992. André Milongo was appointed as transitional prime minister while Sassou remained as president.
