Linda Lee Gustavson (born November 30, 1949), also known by her married name Linda McGuire, is an American former competition swimmer, three-time Olympic medalist, and former world record-holder in two events. As an 18-year-old, she represented the United States at the 1968 Summer Olympics in Mexico City, where she competed in three events and won three medals.
Gustavson was a product of the Santa Clara Swim Club, a powerhouse training program led by coach George Haines. The club was noted for its success in training U.S. Olympic swimmers during the 1960s and 1970s, and produced eight men and eight women members of the 1968 U.S. Olympic swimming team.
She received a gold medal as a member of the first-place U.S. team in the women's 4×100-meter freestyle relay (4:02.5). Together with her teammates Jane Barkman, Sue Pedersen and Jan Henne, she set a new Olympic record of 4:02.5 in the event final. In individual competition, she also won a silver medal in the 400-meter freestyle (4:35.5), and a bronze medal in the 100-meter freestyle (1:00.3).
Gustavson attended Michigan State University with fellow Olympic swimmer Pam Kruse, and the two friends joined Kappa Alpha Theta sorority. She swam for the Michigan State Spartans swimming and diving team in Association for Intercollegiate Athletics for Women (AIAW) and Big Ten Conference competition, and she and Kruse won the Big Ten championship in the 400-yard freestyle relay in 1971. Gustavson graduated from Michigan State in 1972.
