Rebecca Quin (born 30 January 1987) is an Irish professional wrestler and actress currently signed to WWE, where she performs on the SmackDown brand under the ring name Becky Lynch and is the current SmackDown Women's Champion in her second reign.
Quin began training as a professional wrestler under Fergal Devitt and Paul Tracey in June 2002, making her debut five months later. Initially working in Ireland and occasionally teaming with her brother, she soon expanded her career into the rest of Europe on the independent circuit as Rebecca Knox, wrestling regularly for the France-based Queens of Chaos promotion, where she won the World Queens of Chaos Championship in 2006. She also wrestled for England's One Pro Wrestling and Germany's German Stampede Wrestling. She competed in the SuperGirls Wrestling promotion (an offshoot of Extreme Canadian Championship Wrestling), where she was the inaugural SuperGirls Champion and held the championship for ten months and two days. She also appeared at ChickFight III, where she made it to the second round of the tournament. In 2006, she debuted for the all-female Shimmer Women Athletes promotion and was involved in a series of matches with Daizee Haze, including an acclaimed two-out-of-three falls match.
