Yukon general election, 1978

The 1978 Yukon general election, held on November 20, 1978, was the first conventional legislative election in the history of Canada's Yukon Territory. Prior elections were held to elect representatives to the Yukon Territorial Council, a non-partisan body that acted in an advisory role to the Commissioner of the Yukon. Following the passage of the Yukon Elections Act in 1977, the 1978 election was the first time that voters in the Yukon elected representatives to the Yukon Legislative Assembly in an election organized along political party lines.

Hilda Watson, the first woman ever to lead a political party into an election in Canada, was the leader of the Progressive Conservatives. Although the party won the election, Watson herself was defeated in Kluane by Liberal candidate Alice McGuire, and thus did not become government leader. The position of government leader instead went to Chris Pearson.

New Democratic leader Fred Berger was also defeated in his own riding. He remained leader of the party until 1981, when he was succeeded by the party's sole elected MLA, Tony Penikett. Under Penikett's leadership, an MLA who had been elected as an independent in 1978 joined the NDP, and the party won a by-election. With its caucus increased to three members, the NDP had thus supplanted the Liberals as the official opposition by the time of the 1982 election.
