Buchanan Lookout is a historic fire lookout perched in the Selkirk Mountains near Kaslo, British Columbia, at roughly 1,945 metres (6,380 feet) elevation.

Originally built in the early 1940s as a braced-pole tower, it was upgraded over the decades before being decommissioned in 1982. In 1998 it became the first lookout in B. C. recognized by the U. S. -based National Historic Lookout Register.

The site is reached via approximately 12 kilometres of gravel forestry road — rough and not recommended for low-clearance vehicles, campers, or motorhomes — followed by a short 2-kilometre trail.

It is one of the few high-elevation destinations in the province accessible by two-wheel-drive vehicle. From the summit, visitors take in 360-degree views spanning Kokanee Glacier, the Purcell Mountains, and Kootenay Lake.

The area draws hikers, mountain bikers, snowmobilers, and astronomers, with August and September generally offering the most reliable road access.
