Alberta's Rockies in the context of Division No. 15, Alberta

The Canadian Rockies (French: Rocheuses canadiennes) or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast, that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico.

Canada officially defines the Rocky Mountains system as the mountain chains east of the Rocky Mountain Trench extending from the Liard River valley in northern British Columbia to the Albuquerque Basin in New Mexico, not including the Mackenzie, Richardson and British Mountains/Brooks Range in Yukon and Alaska (which are all included as the "Arctic Rockies" in the United States' definition of the Rocky Mountains system). The Canadian Rockies, being the northern segment of this chain, is thus defined as comprising the central-eastern section of the North American Cordillera, between the Prairies of Alberta and the Liard Plain of northeastern British Columbia to the east and the Interior Mountains/Plateau and Columbia Mountains to the west. It is divided into the Northern Rockies (which is further subdivided into the Muskwa and Hart Ranges) and Continental Ranges, separated by the McGregor River valley, the McGregor Pass and the Kakwa River valley.

Banff National Park is Canada's first national park, established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, 110–180 kilometres (68–112 mi) west of Calgary, Banff encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast. The main commercial centre of the park is the town of Banff, in the Bow River valley.

The mountains were formed from sedimentary rocks that were pushed east over newer rock strata, between 80 million and 55 million years ago. Over the past few million years, glaciers have at times covered most of the park; today they are found only on the mountain slopes, though they include the Columbia Icefield, the largest uninterrupted glacial mass in the Rockies. Erosion from water and ice have carved the mountains into their current shapes. Archaeological evidence at Vermilion Lakes indicates presence of Indigenous peoples for more than 10,000 years in the Banff area.

Canmore is a town in Alberta, Canada, located approximately 81 kilometres (50 mi) west of Calgary near the southeast boundary of Banff National Park. It is located in the Bow Valley within Alberta's Rocky Mountains. The town shares a border with Kananaskis Country to the west and south and the Municipal District of Bighorn No. 8 to the north and east. With a population of 17,036 in 2023, Canmore is the fifth-largest town in Alberta.

Jasper National Park, in Alberta, Canada, is the largest national park within Alberta's Rocky Mountains, spanning 11,000 km (4,200 sq mi). It was established as Jasper Forest Park in 1907, renamed as a national park in 1930, and declared a UNESCO world heritage site in 1984. Its location is north of Banff National Park and west of Edmonton. The park contains the glaciers of the Columbia Icefield, springs, lakes, waterfalls and mountains.

Lake Louise is an unincorporated community within Banff National Park in Alberta, Canada. Named after Princess Louise, Duchess of Argyll, it lies in Alberta's Rockies on the Bow River, 3 km (1.9 mi) northeast of the lake that shares its name. Initially settled in 1884 as an outpost for the Canadian Pacific Railway, Lake Louise sits at an elevation of 1,600 m (5,200 ft), making it Canada's highest community.

Banff is a resort town in Banff National Park, Alberta, Canada, in Alberta's Rockies along the Trans-Canada Highway, 126 km (78 mi) west of Calgary, 58 km (36 mi) east of Lake Louise, and 1,400 to 1,630 m (4,590 to 5,350 ft) above sea level.

Banff was the first municipality to incorporate within a Canadian national park. The town is a member of the Calgary Regional Partnership.
