Ange Édouard Poungui (born 1942) is a Congolese politician. Poungui was the Prime Minister of Congo-Brazzaville from 7 August 1984 to 7 August 1989 under President Denis Sassou Nguesso. He was chosen as the candidate of the Pan-African Union for Social Democracy (UPADS) for the 2009 presidential election, but was barred from running.
In December 1969, Poungui was included in the original Political Bureau of the Congolese Labour Party (PCT) as President of the Economy, Finance, and Social Affairs Committee. He was also included in the smaller, five-member Political Bureau elected in December 1971 and was assigned responsibility for finance and equipment. He also served in the government as Minister of Finance until 30 August 1973.
Following the Third Ordinary Congress of the PCT, held on 27–31 July 1984, Poungui was appointed to succeed Louis Sylvain Goma as Prime Minister on 7 August 1984.
Amidst the introduction of multiparty politics, Poungui resigned from the PCT on 28 November 1990 and became the leader of a new party, the Union for Social Progress and Democracy (UPSD). At the end of the June–October 1997 civil war, in which PCT leader Denis Sassou Nguesso returned to power, Poungui, as a supporter of President Pascal Lissouba, fled into exile. He remained in exile until 2006.
Poungui joined UPADS and was elected as one of its 25 Vice-Presidents in December 2006, at the party's first extraordinary congress. He was later chosen as the party's candidate for the 2009 presidential election by the UPADS National Council in a primary election on 30 November 2008. His sole rival for the nomination, Joseph Kignoumbi Kia Mboungou, withdrew from the vote, complaining of "lack of transparency in the process", and Poungui, as the only candidate, received 85% of the vote.
