Snow Dome is a mountain located on the Continental Divide in the Columbia Icefield, where the boundary of Banff National Park and Jasper National Park meets the border of Alberta and British Columbia in Canada.

The mountain was named in 1898 by J. Norman Collie because its permanently snow and ice-capped massif resembles a dome.

[1] The mountain is one of two hydrological apexes of North America; it is a major triple divide between three great drainage basins.

Water falling on Snow Dome's summit may flow into streams that drain into the Pacific Ocean (via the Bush River and the Columbia River), the Arctic Ocean (via the Athabasca River), and Hudson Bay (via the North Saskatchewan River).

The other apex is Triple Divide Peak in Glacier National Park, Montana, United States.
