The FIS Alpine World Ski Championships 1999 were held February 2–14 in Vail and Beaver Creek, Colorado, U.S.A.[1] Lasse Kjus of Norway placed in the top two in all five events, winning two gold medals and taking three silvers.

Hermann Maier of Austria won gold medals in the two speed events, the downhill and super-G (a dead-heat tie with Kjus).

This was the third non-Olympic World Championships held in the United States, all in Colorado.

As a host country, the U.S. has won just two medals in the three World Championships, a gold and a bronze by Tamara McKinney in 1989.

The Birds of Prey downhill course at Beaver Creek was developed for these championships, its first World Cup races were in December 1997.
