The community of Teslin includes the Village of Teslin in Yukon, Canada. Teslin is situated at historical Mile 804 on the Alaska Highway along Teslin Lake. The Hudson's Bay Company established a small trading post at Teslin in 1903.

The Alaska Highway was constructed during World War II to connect the contiguous United States to Alaska across Canada. It begins at the junction with several Canadian highways in Dawson Creek, British Columbia, and runs to Delta Junction, Alaska, via Whitehorse, Yukon. When it was completed in 1942, it was about 2,700 kilometres (1,700 mi) long, but in 2012, it was only 2,232 km (1,387 mi). This is due to the realignments of the highway over the years, which has rerouted and straightened many sections. The highway opened to the public in 1948. Once legendary for being a rough, challenging drive, the highway is now paved over its entire length. Its component highways are British Columbia Highway 97, Yukon Highway 1, and Alaska Route 2.
