Mattie Larson (born May 20, 1992 in Los Angeles) is an elite American gymnast. She is a member of the U.S. National Team and is the 2010 National Champion on floor exercise. Additionally, she was the 2005 Level 10 State, Regional, and National Champion. Her parents, Eric Larson and Gail Boggs, are actors.
Though expected to challenge for a spot on the 2008 U.S. Olympic Team, Larson injured her leg before the final day of the selection camp and could not compete on her best events. Other injuries followed, and she was out of competition for nearly two years.
Larson came back strong in 2010 to win the all-around title at the CoverGirl Classic in July. A month later she won three medals at the 2010 U.S. National Championships: gold on floor, silver in the all-around, and bronze on uneven bars.
Larson signed with the UCLA Gymnastics Team but deferred enrollment to try for the 2012 Olympics in London.
Larson trains with fellow USA Gymnastics National Team member Samantha Shapiro.
