This is a list of the leaders of the opposition of the Yukon Territory, Canada, since 1978 when responsible government was given to the territory. Prior to 1978 the territory had a legislature which had a largely advisory role and no political parties or government leader. Instead powers were invested in a governing commissioner appointed by the federal government.
