Surya Varuna Bonaly (born 15 December 1973 in Nice, France) is a French retired figure skater and coach. She is a three-time World silver medalist (1993–1995), a five-time European champion (1991–1995), the 1991 World Junior Champion, and a nine-time French national champion (1989–1997).

Bonaly is the first Olympic figure skater to land a backflip on one blade; she performed it at the 1998 Winter Olympics in Nagano, Japan, and retired soon afterward. She had a long and successful career as a professional figure skater, performing in ice shows all over the world and winning many professional competitions. She became a coach in Las Vegas, Colorado, Minnesota, and Switzerland.

Surya Varuna Bonaly was born in Nice, France, on 15 December 1973. Her birth name was Claudine; she was adopted out of an orphanage at the age of eight months by Suzanne Bonaly, a physical education teacher in Nice, and Georges Bonaly, a draftsman who worked for the French government, who named her after the Hindu deities Surya and Varuna. Suzanne Bonaly said that they adopted a poor, nonwhite baby because "they are the babies no one takes". They initially wanted to adopt a baby from India, but received a call from an orphanage in France. Bonaly was educated at home by her mother. Bonaly's coach, Didier Gailhaguet, told reporters early in Bonaly's figure skating career that she had been born in Réunion and was abandoned as a baby on the beach, that she had been raised on a macrobiotic diet, and that the 17-inch ponytail she had at the 1992 Olympics had never been cut. Gailhaguet made up these stories about her early life "as a way to contend with better-established" skaters. Bonaly later found that her biological mother was from Réunion and that her biological father was from Ivory Coast.

Bonaly began gymnastics training from her mother when she was two years old and won a silver medal for the trampoline in team tumbling at the 1986 Tumbling World Championships when she was 12 years old. She began figure skating at the age of 12, when she successfully completed her first triple jump. Suzanne Bonaly was her daughter's first skating coach. In 1995, Johnette Howard of Sports Illustrated called Suzanne Bonaly "domineering" and stated that she had "near-total control" of her daughter's training and was intimately involved with her daughter's career. In 2016, reporter Susan Du described Gailhaguet's false stories about Bonaly's birth, the press' reactions to Suzanne Bonaly, and Gailhaguet's unsubstantiated accusations that she had abused her daughter.

Gailhaguet discovered Bonaly and invited her to train with him in Paris; her mother accompanied her there and her father stayed in Nice. Bonaly later told BBC's Outlook Podcast in 2019 that they lived in her parents' van and were "almost homeless". She made the French national team within a year.

Bonaly came in seventh place at Blue Swords, a junior-level competition in Germany, in 1987. At the 1988 World Junior Championships in December 1987, she came in 14th place.

At the 1988 Trophée Lalique, Bonaly came in seventh place. She came in third place at the 1989 World Junior Championships and won the gold medal for the first time at the 1989 French National Championships in December 1988. She came in eighth place at the 1989 European Championships and in 10th place at the 1989 World Championships.

In the fall of 1989, Bonaly competed at the Nebelhorn Trophy, where she came in second place, and at Skate America, where she came in sixth place. She again won the gold medal at the French Nationals and came in second place at Junior Worlds. She came in seventh place at the 1989 Tropheé Lalique, in fourth place at Europeans, and in ninth place at Worlds.
