Wapta Icefield, Continental ice field in Canadian Rockies, Alberta and British Columbia, Canada

Wapta Icefield is a series of glaciers on the Continental Divide in the Waputik Mountains, straddling the Alberta–British Columbia border within Banff and Yoho National Parks. Outlet glaciers such as the Vulture, Bow and Peyto Glaciers extend from it, and five Alpine Club of Canada huts stand across the icefield for mountaineers.

The icefield is one of the most studied in the Canadian Rockies, and all evidence shows it shrinking, especially at the low ends of its outlet glaciers. In the 1980s it covered about 80 km2 (30 sq mi). The Crowfoot Glacier, once joined to it, has since separated as the ice retreated.

The name Wapta comes from a Stoney word meaning "river", not from Cree. The icefield straddles the Continental Divide, so its meltwater leaves in opposite directions: Peyto and Vulture glaciers drain toward the Alberta side, while Yoho Glacier feeds the Yoho River, which reaches the Columbia and the Pacific. The Yoho name itself derives from a Cree word for awe.

The icefield lies on the Continental Divide in the Waputik Mountains, shared by Banff and Yoho National Parks. Winter ski traverses and summer glacier hikes often continue south across the Waputik Icefield. Five Alpine Club of Canada huts stand on the icefield, among them the Bow, Peyto, Balfour, Guy and Scott Duncan huts.

The Burgess Shale animal Waptia takes its name from the Wapta Icefield. The same meltwater that feeds the icefield's outlet glaciers also feeds Wapta Falls, and the icefield's runoff reaches both the Kicking Horse and Bow Rivers.
