Katja Seizinger (German pronunciation: [ˈkatja ˈzaɪtsɪŋɐ] ⓘ; born 10 May 1972) is a German former World Cup alpine ski racing champion.

She is her country's most successful alpine skier.

[2] Born in Datteln, North Rhine-Westphalia, Seizinger won three Olympic gold and two bronze medals, and won eleven World Cup season titles: two overall, four downhill, and five Super-G. She was a three-time winner of Germany's sportswoman of the year award.

With Olympic downhill victories in 1994 and 1998, she was the first to win consecutive Olympic gold medals in the same alpine speed event, and also the first woman to successfully defend an Olympic alpine title.

[3][4] Seizinger injured both knees while training in June 1998,[5] missed the entire 1999 season,[6] then retired in April.
