Casey Joel Stoner (born 16 October 1985 in Southport, Queensland, Australia) is a retired Australian professional motorcycle racer, and a two-time MotoGP World Champion, in 2007 and 2011. Stoner currently serves as a test and development rider for Ducati.

Stoner secured a ride with the factory Ducati team for the 2007 season, joining Loris Capirossi on the new 800cc Ducati Desmosedici GP7. 6 poles and 10 race wins (including three of the first four), took him to his first GP title, by a margin of 125 points (equivalent to five victories) over Dani Pedrosa, which he built during the second half of the season. His worst finish was a 6th place at Motegi, which was all he needed to clinch the title that day, taking the first premier class title for an Italian manufacturer since Phil Read's title for MV Agusta in 1974. Stoner was named Young Australian of the Year for his 2007 performance.
