The Yukon Legislative Assembly is the legislative assembly for Yukon, Canada. Unique among Canada's three territories, the Yukon Legislative Assembly is the only territorial legislature which is organized along political party lines. In contrast, in Nunavut and the Northwest Territories, their legislative assemblies are elected on a non-partisan basis and operate on a consensus government model.

Yukon is the smallest and westernmost of Canada's three territories. It is the third-least populated province or territory in Canada, with a population of 45,148 as of 2023. However, Whitehorse, the territorial capital, is the largest settlement in any of the three territories.
