Béla Károlyi (; born September 13, 1942) is an ethnic Hungarian Romanian-American gymnastics coach. Early in his coaching career he developed the Romanian centralised training system for gymnastics. One of his earliest protégés was Nadia Comăneci, the first Olympic Games gymnast to be awarded a perfect score. Living under the dictatorship of Nicolae Ceaușescu, Károlyi frequently clashed with Romanian officials. He and his wife defected to the United States in 1981. Since their arrival in the United States, Béla and his wife Márta Károlyi have been credited with transforming the coaching of gymnastics in the US and bringing major international success. They have both been head coach of the United States women's national gymnastics team, as well as national team coordinator for United States gymnastics at the Olympic Games. They have also been severely criticized for their coaching style, which many gymnasts have called abusive. They have said they had no clue that Larry Nassar, the national gymnastics team doctor who was convicted of sexual assault of minors, was assaulting young female gymnasts in their care at their Karolyi Ranch training facility in Texas. The Karolyis and their ranch are central figures in 2020 film, Athlete A - a documentary about the scandal. Károlyi has coached many notable national, European, World and Olympic gymnasts, including Nadia Comăneci, Ecaterina Szabo, Mary Lou Retton, Betty Okino, Teodora Ungureanu, Kim Zmeskal, Kristie Phillips, Dominique Moceanu, Phoebe Mills, and Kerri Strug. In total, Károlyi has coached nine Olympic champions, fifteen world champions, sixteen European medalists, and six U.S. national champions. Béla Károlyi was inducted into the International Gymnastics Hall of Fame in 1997. Béla and Márta Károlyi as a coaching team were inducted into the US Gymnastics Hall of Fame in 2000.
