Yukon (Canadian French: [jukõ]) is a territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada's westernmost and smallest territory by land area. As of the 2021 census, Yukon is the middle of the three territories in terms of population, but the most densely populated. As of the 2025 third quarter estimates Yukon had a population of 48,278, which would make it the most populated territory. Whitehorse, the territorial capital, is the largest settlement.
Yukon was split from the Northwest Territories by a federal statute in 1898 as the Yukon Territory. The current governing legislation is the Yukon Act passed by the federal Parliament in 2002. That act established Yukon as the territory's official name, although Yukon Territory remains in popular usage. Canada Post uses the territory's internationally approved postal abbreviation of YT. In 2021, territorial government policy was changed so that The Yukon is recommended for use in official territorial government materials.
