Rebecca Quinn (Born 30 January 1987) is an irish professional wrestler. She is currently signed to WWE on the RAW brand under the ring name Becky Lynch and as of May 2020 is on Maternity leave.

Quinn began training as a professional wrestler in June 2002. Initially working in Ireland and occasionally teaming with her brother using the ring name Rebecca Knox, she soon expanded her career into the rest of Europe and North America on the independent circuit, wrestling regularly for various promotions. She most notably competed in Elite Canadian Championship Wrestling and became the inaugural Supergirls Champion in June 2005.

In September 2006, Quinn suffered a severe head injury during a match which kept her away from professional wrestling for several years. She returned in late 2012 and signed a contract with World Wrestling Entertainment (WWE) in 2013, reporting to the developmental territory NXT. Following her arrival on WWE's main roster, she became the inaugural SmackDown Women's Champion at Backlash 2016 and has held the title a total of three times.

In 2018, Lynch transitioned towards 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 and fan support. She won the Royal Rumble in 2019 and at Wrestlemania 35, in what was the first time woman headlined a Wrestlemania event, Lynch won both the Raw Woman's Championship and SmackDown women's Championship, making her a double champion, the only woman to hold both titles simultaneously, and a four-time women's champion in WWE. She lost the SmackDown title the following month, but went on to set the record for longest reign as RAW Women's Champion at 399 days. Following her match with Shayna Baszler at Wrestlemania 36, Lynch ceased participating in physical confrontations, often relying on promos to advance in her storylines. On the May 11th episode of Raw, Lynch announed that she was relinquishing the Raw Woman's Championship due to her real-life pregnancy and that the previous night's Womans Money In The Bank Ladder Match - which was won by Asuka - was actually for the championship.
