This article is about an ecozone and should not be confused with articles covering the physiographic regions covering the same area, which are the Canadian Rockies, Columbia Mountains, and portions of the Thompson Plateau.

The Montane Cordillera is an Ecozones of Canacookies in south-central British Columbia and southwestern Alberta, Canada (an ecozone is equivalent to a Level I ecoregion in the United States). A rugged and mountainous ecozone spanning 473,000 square kilometres, it still contains "two of the few significant agricultural areas of the province", the Creston Valley and the Okanagan Valley. Primarily a mountainous region, it consists of rugged ecosystems such as alpine tundra, dry sagebrush and dense conifer forests. The interior plains are encircled by a ring of mountains. The area has a mild climate throughout the year, with typically dry summers and wet winters.
