Yukon /ˈjuːkɒn/ is the westernmost and smallest of Canada's three federal territories.

The territory was created from the rump of the Hudson's Bay Company's North-Western Territory in 1898 as "the Yukon". Receiving royal assent on March 27, 2002, the federal government moderized the Yukon Act to confirm "Yukon", rather than "Yukon Territory", as the current usage standard. Though officially bilingual (English and French) the Yukon Government also recognizes First Nations languages.

At 5,959 m (19,551 ft), Yukon's Mount Logan, in Kluane National Park and Reserve, is the highest mountain in Canada and the second-highest of North America (after Mount McKinley in the U.S. state of Alaska). The territory's climate is Arctic and subarctic, resulting in long cold winters, short summers, and little precipitation.
