Simone Arianne Biles Owens (née Biles; born March 14, 1997) 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 Olympians of all time. With 11 Olympic medals, she is tied with Věra Čáslavská as the second-most decorated female Olympic gymnast, 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. She won a silver medal with the United States team nicknamed the "Fighting Four". At the World Championships, she is the most decorated - male or female - artistic gymnast of all time with 30 total medals in which 23 of them are Gold. Biles is a six-time individual all-around champion (2013, 2014, 2015, 2018, 2019 and 2023), six-time floor exercise champion (2013–2015, 2018–2019, 2023), and four-time balance beam champion (2014–2015, 2019, 2023), all record-high totals. She is also a two-time vault champion (2018–2019) and a member of a record-high five gold medal-winning United States teams (2014–2015, 2018–2019, 2023). She is also a four-time World silver medalist (2013–2014 and 2023 on vault, 2018 on uneven bars), a three-time World bronze medalist (2015 on vault, 2013 and 2018 on balance beam). Domestically, Biles has won a record-high nine United States national all-around championships (2013–2016, 2018–2019, 2021, 2023–2024); her win in 2024 made her the oldest female gymnast to ever win the title. She is also a seven-time champion on vault, balance beam, and floor exercise, a two-time uneven bars champion, and the only woman to win all five gold medals in a single championships twice (2018, 2024). Biles is the sixth woman to win an individual all-around title at both the Olympics and the World Championships and the first since Lilia Podkopayeva in 1996 to hold both titles simultaneously. She is the tenth female gymnast and first American female gymnast to win a World medal on every event, and the first female gymnast since Daniela Silivaș in 1988 to win a medal on every event at a single Olympics or World Championships. Biles is the originator of the most difficult skill on women's vault, balance beam, and floor exercise and the only gymnast to attempt each skill to date. In 2022, President Joe Biden awarded her the Presidential Medal of Freedom. In 2023, she won her eighth U.S. Gymnastics title, breaking the 90-year-old U.S. Gymnastics title record previously held by Alfred Jochim. Biles has won the Laureus World Sportswoman of the Year four times (2017, 2019, 2020, 2025) and Comeback of the Year once (2024).
