The northwestern wolf (Canis lupus occidentalis), also known as the Mackenzie Valley wolf,[5] Alaskan timber wolf,[6] or Canadian timber wolf,[7] is a subspecies of gray wolf in western North America. Arguably the largest gray wolf subspecies in the world, it ranges from Alaska, the upper Mackenzie River Valley; southward throughout the western Canadian provinces, aside from prairie landscapes in its southern portions, as well as the Northwestern United States.[6]
