Alexandra Meissnitzer (born 18 June 1973) is a retired World Cup alpine ski racer from Austria.

From Abtenau, Salzburg, her father, Hans Meissnitzer, a mechanic by trade, taught her to ski at an early age.

At the 1998 Winter Olympics at Nagano, Meissnitzer won the silver in the giant-slalom and the bronze in the super-G, and at the 2006 Winter Olympics at Turin she won the bronze in the super-G.

At the 2003 World Championships, she won the silver medal in the downhill race (in a tie with Corinne Rey-Bellet) behind Melanie Turgeon.

Meissnitzer was third in the super-G at the 2008 World Cup finals in Bormio, Italy, and became the oldest woman (age 34) to finish on the podium in an alpine World Cup race.
