The '''Crowsnest Highway''' is an east-west highway in [[British Columbia]] and [[Alberta]], [[Canada]]. It stretches {{cvt|1161|km|mi}} across the southern portions of both provinces, from [[Hope, British Columbia]] to [[Medicine Hat|Medicine Hat, Alberta]], providing the shortest highway connection between the [[Lower Mainland]] and [[southern Alberta|southeast Alberta]] through the [[Canadian Rockies]]. Mostly two-lane, the highway was officially designated in 1932, mainly following a mid-19th-century gold rush trail originally traced out by an engineer named [[Edgar Dewdney]].  It takes its name from the [[Crowsnest Pass]], the location at which the highway crosses the [[Continental Divide]] between British Columbia and Alberta.

In [[British Columbia]], the highway is entirely in mountainous regions and is also known as the Southern Trans-Provincial Highway. The western-most segment between the [[Trans-Canada Highway]] and [[British Columbia provincial highway 5A|Highway 5A]] is locally known as the [[Hope, British Columbia|Hope]]-[[Princeton, British Columbia|Princeton]] Highway, and passes by the site of the [[Hope Slide]]. In Alberta, the terrain is initially mountainous, before smoothing to foothills and eventually generally flat prairie in the vicinity of Pincher Creek. The highway forms part of the [[Red Coat Trail]] and the [[CANAMEX Corridor]] from [[Alberta Highway 2|Highway 2]] near [[Fort Macleod]] to [[Alberta Highway 4|Highway 4]] in [[Lethbridge, Alberta|Lethbridge]].
Many sections of the highway were built by Japanese labour while they were [[Japanese Canadian internment|interned]] during the Second World War, including sections like the Hope-Princeton. This history has been preserved at a heritage marker at [[Sunshine Valley, British Columbia|Sunshine Valley]], which was the largest internment camp in Canada.
