Sonnie Trotter (born 15 November 1979) is a Canadian professional climber, known for his strength in many rock climbing disciplines – particularly traditional climbing – and contributing to hundreds of first free ascents around the world.
In later years, Trotter became known for his traditional climbing routes, and his first free ascent of the Cobra Crack in Squamish, British Columbia.
In 2006, Trotter and climbing partner Matt Segal, connected The Shadow (5.13b), The Grand Wall (5.13b), and The Black Dyke (5.13b), on the Stawamus Chief in Squamish, in a single 12-hour push.
"If you're not falling" won Best Short Film at BIMFF in 2008 and "First Ascent" is the winner of multiple awards.
Trotter is also prominently featured in the opening scenes of the hit motion picture 'The Twilight Saga: Breaking Dawn - Part 2' being chased by Bella while free soloing.
