The Taiga Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a rugged, mountainous terrestrial ecozone of Canada spanning most of northern Yukon and significant portions of the border between the Yukon and the Northwest Territories.
This ecozone is very sparsely populated, with only a few hundred inhabitants who rely on subsistence living and the tourism industry. Most of the area's population consists of members of the Vuntut Gwitchin First Nation in the community of Old Crow, located on the Porcupine River.
The area includes three national parks within its boundaries - Ivvavik National Park, Vuntut National Park, and Nahanni National Park Reserve, one of twelve sites in the first group of World Heritage Sites granted by UNESCO. It also contains Old Crow Flats, an internationally important wetland that overlaps Vuntut National Park.
To the south is the Boreal Cordillera, to the east are the Taiga Plains, and its northern extent is defined by Yukon's coastline, at which it abuts the Arctic Archipelago Marine ecozone.
