The FIS Alpine World Ski Championships 2009 were the 40th FIS Alpine World Ski Championships, held 2–15 February in France at Val-d'Isère, Savoie.

The International Ski Federation (FIS) awarded the championships to Val-d'Isère on 2 June 2004, in Miami, Florida.

The other two finalists were Vail/Beaver Creek, USA, and Schladming, Austria, which was later selected to host the 2013 championships.

These were the first world championships at Val-d'Isère, although the area hosted four of the five men's events at the 1992 Winter Olympics in Albertville (the slalom was held at Les Menuires).

Val-d'Isère is a regular stop on the World Cup circuit, usually by the men in early to mid-December.
