Charles Joseph "Joe" Clark, PCCCAOE (born June 5, 1939) is a Canadian statesman, businessman, writer, and politician who served as the 16th Prime Minister of Canada, from ******, 1979, to March 3, 1980.

Despite his relative inexperience, Clark rose quickly in federal politics, entering the House of Commons in the 1972 election and winning the leadership of the Progressive Conservative Party in 1976. He came to power in the 1979 election, defeating the Liberal government of Pierre Trudeau and ending 16 years of continuous Liberal rule. Taking office the day before his 40th birthday, Clark is the youngest person to become Prime Minister. His tenure was brief as he only won a minority government, and it was defeated on a motion of non-confidence. Clark's Progressive Conservative Party subsequently lost the 1980 election and Clark lost the leadership of the party in 1983.
