Joseph Jacques Jean Chrétien PC OM CC QC (born January 11, 1934), known commonly as Jean Chrétien (French pronunciation: ) is a former Canadian politician who was the 20th Prime Minister of Canada. He served in the position for over ten years, from November 4, 1993 to December 12, 2003.

Born and raised in Shawinigan, Quebec, Chrétien is a law graduate from Université Laval. He was first elected to the Canadian House of Commons in 1963. He served in various cabinet posts under prime minister Pierre Trudeau, most prominently as Minister of Justice, Minister of Finance, and Minister of Indian Affairs and Northern Development. He also served as deputy prime minister in John Turner's short-lived government. He became leader of the Liberal Party of Canada in 1990, and led the party to a majority government in the 1993 federal election. He was re-elected with further majorities in 1997 and 2000.

Chrétien was strongly opposed to the Quebec sovereignty movement and supported official bilingualism and multiculturalism. He won a narrow victory as leader of the federalist camp in the 1995 Quebec Referendum, and then pioneered the Clarity Act to avoid ambiguity in future referendum questions. He also advanced the Youth Criminal Justice Act in Parliament. Although his popularity and that of the Liberal Party were seemingly unchallenged for three consecutive federal elections, he became subject to various political controversies in the later years of his premiership. He was accused of inappropriate behaviour in the Sponsorship Scandal, although he has consistently denied any wrongdoing. He also became embroiled in a protracted inner-party struggle against long-time political rival Paul Martin. He resigned as prime minister in December 2003, and left public life.
