The 1963 Canadian federal election was held on April 8, 1963 to elect members of the House of Commons of Canada of the 26th Parliament of Canada. It resulted in the defeat of the minority Progressive Conservative (Tory) government of Prime Minister John Diefenbaker, with the Liberals returning to power for the first time in 6 years, where they would remain for twenty of the next twenty-one years. For the Social Credit Party, despite getting their highest ever share of the vote, the party lost 6 seats compared to its high-water mark in 1962.

The Progressive Conservative Party of Canada was a centre to centre-right federal political party in Canada that existed from 1942 to 2003.
