Cobra Crack is a 45-metre (148-foot) long traditional climbing route on a thin crack up an overhanging granite rock face on Stawamus Chief, in Squamish, British Columbia. The route was first ascended by Peter Croft and Tami Knight in 1981 as an aid climb. After it rebuffed many leading climbers, most notably Swiss climber Didier Berthod in 2005, the Canadian climber Sonnie Trotter made the first free ascent in 2006. With subsequent ascents, the consensus grade has settled at 5.14b (8c), which ranked the route as one of the hardest crack climbs in the world, and almost two decades later, it is still considered one of the world's hardest traditional climbing routes.
