Simone Arianne Biles Owens is an American artistic gymnast. Her 11 Olympic medals and 30 World Championship medals make her the most decorated gymnast in history. She is widely regarded as one of the greatest gymnasts of all time, and one of the greatest female athletes in history. With 11 Olympic medals, she is tied with Věra Čáslavská as the second-most decorated female Olympic gymnast behind Larisa Latynina, and has the most Olympic medals earned by a U.S. gymnast.
At the Olympic Games, Biles is a two-time gold medalist in the individual all-around (2016, 2024). She is also a two-time champion on vault (2016, 2024), the 2016 champion and 2024 silver medalist on floor exercise, and a two-time bronze medalist on balance beam (2016, 2020). Biles led the gold medal-winning United States teams in 2016, dubbed the "Final Five," and in 2024, dubbed the "Golden Girls". At the 2020 Summer Olympics, where she was favored to win at least four of the six available gold medals, she withdrew from most of the competition after the qualification round due to "the twisties", a temporary loss of air awareness while performing twisting elements.
