The Yukon tartan is composed of green, dark blue, magenta, yellow and white stripes in varying widths on a light blue background.
The crystalline blue background represents Yukon's sky and the green symbolizes the territory's forests. White symbolizes snow and yellow represents Yukon's gold. Magenta is the colour of fireweed, Yukon's official flower, and dark blue represents the mountains.
The Yukon tartan was designed by Janet Couture of Watson Lake in 1965 and was first proposed as the official territorial tartan during the 1967 Canadian centennial celebrations. The tartan was later accepted by the King of Arms of Her Majesty's New Registry House in Edinburgh in October 1984. The Yukon Tartan Act was passed in 1984.
