The Arctic Cordillera is a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through icefields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.

The range is mostly located in Nunavut but extends southeast into the northernmost tip of Labrador and northeastern Quebec. The system is divided into a series of ranges, with mountains reaching heights more than 2,000 m (6,562 ft). The highest of the group is Barbeau Peak on Ellesmere Island at 2,616 m (8,583 ft), which is the highest point in eastern North America. The system is also one of Canada's three mountain systems, the others being the Western Cordillera of Western Canada and the Canadian extension of the Appalachian Mountains into the Gaspé Peninsula and Atlantic Provinces.

The Arctic Cordillera is a narrow ecozone compared to other Canadian ecozones. The majority of this ecozone borders the Northern Arctic, while the small segment within Labrador borders the Taiga Shield. However, bordering the Taiga Shield seems to affect neither itself nor the ecozones it borders because their biological properties appear to be opposites (cold climate versus warm climate; different species of plants and animals). While the Arctic Cordillera mountain system includes most of the Arctic islands and regions such as Bathurst Island, Cornwall Island, Amund Ringnes Island, Ellef Ringnes Island, Ellesmere Island, Baffin Island, Bylot Island and Labrador, the Arctic Cordillera Ecozone only covers Ellesmere Island, Baffin Island, Axel Heiberg Island, Bylot Island and Labrador.
