Katie Taylor

Katie Taylor (born 2 July 1986) is an Irish Olympian, professional boxer and former footballer. She was the undisputed and undefeated lineal world lightweight champion from 2019 to 2024, and has held the unified and lineal world super lightweight championship since 2023. Hugely popular in Ireland, she is credited with raising the profile of women's boxing at home and abroad, and is regarded as the outstanding Irish athlete of her generation. She is considered by many to be the greatest female boxer of all time.

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. She was the flag bearer for Ireland at the 2012 London Olympics opening ceremony before going on to win the gold medal in the lightweight division.

Taylor turned professional in 2016 under Matchroom Boxing. After winning the WBA lightweight title in 2017 and the IBF title the following year, her unification victory over Delfine Persoon in Madison Square Garden made her the eighth boxer in history (female or male) to hold all four major world titles in boxing—IBF, WBA, WBC, and WBO—simultaneously. In November 2023 she repeated the feat at super lightweight when she beat Chantelle Cameron in Dublin for the IBF, IBO, WBA, WBC, and WBO titles, regaining the latter she initially won from Christina Linardatou in 2019.

As of September 2025, Taylor is ranked as the world's best active female super lightweight by BoxRec and the best active female boxer, pound-for-pound, by The Ring and BoxRec. She is known for her fast-paced, aggressive boxing style.
