The Yellowhead Pass is a mountain pass across the Continental Divide of the Americas in the Canadian Rockies. It is located on the provincial boundary between the Canadian provinces of Alberta and British Columbia, and lies within Jasper National Park and Mount Robson Provincial Park. Due to its modest elevation of and its gradual approaches, the pass was recommended by Sir Sandford Fleming as a route across the Rocky Mountains for the planned Canadian Pacific Railway. This proposal was rejected in favour of a more direct and southerly route through the more difficult Kicking Horse Pass, opened in 1886. However, both the Grand Trunk Pacific and Canadian Northern Railways used the Yellowhead Pass for their main lines built c. 1910–1913, and the main line of their successor, the Canadian National Railway, still follows the route. Via Rail's premier passenger train, the Canadian, uses the CN tracks as does the Jasper – Prince Rupert train and the Jasper section of the Rocky Mountaineer. The pass is now also traversed by the Yellowhead Highway.
