Rosemarie "Rosi" Mittermaier-Neureuther (born 5 August 1950, Reit im Winkl, Bavaria, Germany) is a retired World Cup alpine ski racer. She won two gold medals and one silver at the 1976 Winter Olympics in Innsbruck, Austria, becoming the most successful athlete there along with Raisa Smetanina of Soviet Union, and earning her the nickname of Gold-Rosi within Germany (then West Germany).
Mittermaier made her World Cup debut in the inaugural season of 1967 at age 16, won her first World Cup race two seasons later, and retired from international competition following the very successful 1976 season, at age 25. In addition to the overall World Cup title, she also won the season title in slalom and combined in 1976.
Today, she works for several charities and occasionally as a commentator for German television for major sporting events. She is married to Christian Neureuther, winner of six World Cup slalom races, and is the mother of Felix Neureuther, a World Cup ski racer for Germany.
