Didier Cuche (born August 16, 1974, in Le Pâquier, Neuchâtel) is a Swiss alpine ski racer. He primarily competes in the speed disciplines of downhill and Super-G, along with the technical discipline of giant slalom. He is the reigning World Cup downhill champion for the 2010 season and has won two previous downhill titles in 2007 and 2008, along with a giant slalom title in 2009. Through January 2011, Cuche has 16 World Cup race victories, along with 59 podiums (top three) and 166 top ten finishes. He is also an Olympic silver medalist and has won a total of four World Championships medals (a gold, two silvers, and a bronze).
At the 1998 Winter Olympics in Nagano, Japan, Cuche was the silver medalist in the Super-G, where he had exactly the same time as Hans Knauss resulting in a rare sharing of the medal (no bronze medal was awarded).
Cuche switched from Atomic to Head skis following the 2006 season, joining Bode Miller and Hermann Maier.
