Conor Anthony McGregor (born 14 July 1988) is an Irish professional mixed martial artist and boxer. He is the former Ultimate Fighting Championship (UFC) featherweight and lightweight champion. He has also competed as a welterweight in mixed martial arts (MMA), and light middleweight in boxing. He is #3 on the UFC's pound for pound rankings.
McGregor started his MMA career in 2008 and, in 2012, he won both the Cage Warriors Featherweight and Lightweight Championships, holding both titles simultaneously before vacating them to sign with the UFC. In 2015, at UFC 194, he defeated José Aldo for the UFC Featherweight Championship via knockout thirteen seconds into the first round, which is the fastest victory in UFC title fight history.
Upon defeating Eddie Alvarez for the UFC Lightweight Championship at UFC 205, McGregor became the first fighter in UFC history to hold titles in two weight divisions simultaneously.
McGregor began his professional boxing career in 2017. In his debut boxing match, he was defeated by Floyd Mayweather Jr.
McGregor is the biggest pay-per-view (PPV) draw in MMA history, having headlined four out of the six highest-selling UFC pay-per-view events. His headline bout with Nate Diaz at UFC 202 drew 1.65 million PPV buys, the most ever for an MMA event. His boxing match with Mayweather drew 4.3 million PPV buys in North America, the second most in history.
