Rebecca Quin (born 30 January 1987), better known by the ring name Becky Lynch, is an Irish professional wrestler. She has been signed to WWE since April 2013, where she performs on the Raw brand. Lynch is often regarded as one of the greatest women's professional wrestlers of all time.Quin began training as a professional wrestler in 2002. Initially working in Ireland, and occasionally teaming with her brother using the ring name Rebecca Knox, she soon began wrestling across Europe and North America on the independent circuit for various promotions. She most notably competed in Elite Canadian Championship Wrestling and became the inaugural SuperGirls Champion in 2005. In 2006, Quin had a severe head injury during a match which kept her away from wrestling for several years. She returned in 2012 and signed a contract with WWE in 2013, assigned to the developmental territory at NXT. Following her push to WWE's main roster, she became the inaugural SmackDown Women's Champion at Backlash 2016 and has held the title five times. In 2018, Lynch transitioned to a more aggressive character starting at SummerSlam, when she attacked Charlotte Flair, presenting herself as an unfairly treated underdog and dubbing herself "The Man", resulting in a large increase in her popularity. In 2019, she won the Royal Rumble match, and in the main event of WrestleMania 35 won both the Raw Women's Championship and SmackDown Women's Championship, making her the first woman to hold both titles simultaneously and a four-time WWE women's champion. This was also the first time that a women's match was the main event of a WrestleMania, which was also subsequently the final one-night WrestleMania as it expanded to two nights the following year. She stands as one of only five women to have headlined WWE's marquee event.
