Debra Rae Armstrong (born December 6, 1963) is a former World Cup alpine ski racer from Seattle, Washington. She was the first Olympic gold medalist from the U.S. in women's alpine skiing in twelve years, winning the giant slalom at the 1984 Winter Olympics in Sarajevo, Yugoslavia.

Born in Salem, Oregon, Armstrong grew up in Seattle and was a multi-sport athlete at Garfield High School; in addition to ski racing, she also played basketball, soccer, volleyball, and tennis. Armstrong has been inducted in the Seattle Public Schools Hall of Fame, State of Washington Sports Hall of Fame, and the National Ski Hall of Fame.

Armstrong developed her racing skills in the 1970s at the Alpental ski area at Snoqualmie Pass, an hour east of Seattle on I-90. The run "Debbie's Gold" and the "Armstrong's Express" high-speed quad chairlift are named for her.
