The 1983 Progressive Conservative leadership election was held on June 11, 1983, in Ottawa to choose a new party leader after Joe Clark resigned. The party started with eight candidates and ended with Brian Mulroney winning on the fourth ballot. Erik Nielsen had been the interim leader.

Key candidates
- Brian Mulroney: Toronto-area businessman and lawyer, fluent in French, seen as a strong choice to win Quebec and form a national government.
- Joe Clark: the former prime minister who had led the PCs since 1976 and hoped to win a clear mandate to stay on as leader.
- John Crosbie: Newfoundland MP and former finance minister, known for his sharp debating style but not fluent in French.
- Michael Wilson, David Crombie, Peter Pocklington, John Gamble, and Neil Fraser were also in the race. The campaign drew on a mix of pro-business and more centrist, or regional, factions.

Quebec and language played a big role. Mulroney’s ability to speak French and appeal to Quebec voters gave him a major edge over rivals like Crosbie, who could not speak French well, and over Clark, who faced challenges uniting the party in English Canada with Quebec voters.

The convention and ballots
- The party chose delegates through a system where a candidate needed a simple majority (50% + 1). If no one reached it, the last-place candidate was eliminated and new ballots were held.
- After the early rounds, the field was narrowed from eight to four, then to two.
- Endorsements helped shape the second and later ballots. Wilson and Pocklington backed Mulroney; Gamble and Fraser backed Crosbie; Crombie endorsed Crosbie after being eliminated.
- On the final, fourth ballot, Mulroney defeated Clark by a comfortable margin: about 54.4% to 45.6%.

What happened next
- Mulroney became leader and led the Progressive Conservatives to a landslide victory in the 1984 federal election.
- Clark, Crosbie, Crombie, and Wilson all went on to hold prominent positions in Mulroney’s cabinet.
- The party adopted a pro-business, free-trade stance, including the Canada-U.S. Free Trade Agreement, and pursued closer ties with Quebec on constitutional matters.
- The leadership contest highlighted deep divisions within the party but ultimately helped Mulroney unify many factions around his bid to return the PCs to power.

Aftermath and legacy
- The 1983 leadership drama set the stage for a major realignment in Canadian politics, with the PCs dominating the mid-1980s under Mulroney.
- Clark would later return as party leader in 1998, serving until 2002.
