Simone Arianne Biles (born March 14, 1997)[4] is an American artistic gymnast. Biles is the 2016 Olympic individual all-around, vault and floor gold medalist. She was part of the gold medal-winning team dubbed the "Final Five" at the 2016 Summer Olympics in Rio de Janeiro. She also won the bronze medal for the balance beam during the Olympics. Biles is a three-time world all-around champion (2013–15), three-time world floor champion (2013–15), two-time world balance beam champion (2014, 2015), four-time United States national all-around champion (2013–16), and a member of the gold medal-winning American teams at the 2014 and 2015 World Artistic Gymnastics Championships.

Having won a combined total of nineteen Olympic and World Championship medals, Biles is the most decorated American gymnast, taking over from Shannon Miller, who had held this record since 1996. With her win in Rio, Biles became the sixth woman to have won an individual all-around title at both the World Championships and the Olympic Games. With four Olympic gold medals, Biles set an American record for most gold medals in women's gymnastics at a single Games.
