The 1988 Canadian federal election was held on November 21, 1988, to elect members to the House of Commons of Canada of the 34th Parliament of Canada. It was an election largely fought on a single issue: the Canada–United States Free Trade Agreement (CUSFTA); the Progressive Conservative Party campaigned in favour of it, whereas the Liberal Party and the New Democratic Party (NDP) campaigned against it. Mulroney won a governing majority and the agreement was passed into law, even though a majority of the voters had voted for parties opposing free trade. The Mulroney government instituted the Goods and Services Tax during this term as well.

The 34th Canadian Parliament was in session from December 12, 1988, until September 8, 1993. The membership was set by the 1988 federal election on November 21, 1988, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1993 election.
