The 25th World Cup season began in August 1990 in New Zealand (for men only), resumed in December, and concluded in March 1991 in the United States.

The overall winners were Marc Girardelli of Luxembourg, his fourth title (the third man to reach that milestone) and Petra Kronberger of Austria (her second).

During this season, the three men's races at Wengen were cancelled after the death of Gernot Reinstadler of Austria on January 18.

Reinstadler crashed during a training run for the downhill race, immediately above the finish line.
