Highway 5 is a 543 km (337 mi) north–south route in southern British Columbia, Canada. Highway 5 connects the southern Trans-Canada route (Highway 1) with the northern Trans-Canada/Yellowhead route (Highway 16), providing the shortest land connection between Vancouver and Edmonton. Despite the entire route being signed as part of the Yellowhead Highway, the portion of Highway 5 south of Kamloops is also known as the Coquihalla Highway, while the northern portion is known as the Southern Yellowhead Highway. The Coquihalla section was a toll road until 2008.
Although the Yellowhead Highway system is considered part of the Trans-Canada Highway network, Highway 5 is not represented with a Trans-Canada marker. Regardless, Highway 5 is designated as a core route of Canada's National Highway System.
