Katie Taylor is an Irish professional boxer and former footballer. She is a two-weight world champion and the current undisputed lightweight champion, having held the WBA title since 2017; the IBF title since 2018; and the WBC, WBO, and Ring magazine titles since 2019, as well as having held the WBO junior-welterweight title in 2019. Following her victory over Delfine Persoon in 2019, she became one of only eight boxers in history (female or male) to hold all four major world titles in boxing—WBA, WBC, IBF, and WBO—simultaneously.
In her amateur boxing career, Taylor won five consecutive gold medals at the Women's World Championships, gold six times at the European Championships, and gold five times at the European Union Championships. Hugely popular in Ireland, she is credited with raising the profile of women's boxing at home and abroad. Regarded as the outstanding Irish athlete of her generation, she was the flag bearer for Ireland at the 2012 London Olympics opening ceremony before going on to win an Olympic gold medal in the lightweight division.
