Conor McGregor

Conor McGregor (born July 14, 1988, Dublin, Ireland) is an Irish mixed martial artist who became the most famous name in the sport after winning Ultimate Fighting Championship (UFC) titles in two different weight classes in 2015–16. McGregor’s meteoric rise and worldwide celebrity has come with much controversy, the result of an exceptionally brash persona and frequent run-ins with the law.

Background

The youngest of three children, McGregor grew up in Crumlin, a working-class suburb of Dublin. His father, Tony McGregor, was a taxi driver, and his mother, Margaret (née Moore) McGregor, was a laundry worker. McGregor went to Irish-speaking primary and secondary schools and played football (soccer) as a youth. At age 12 he signed up for boxing lessons at the Crumlin Boxing Club, where his athletic talent was recognized and nurtured by Phillip Sutcliffe, the club’s head coach. Soon McGregor began training in kickboxing and mixed martial arts (MMA) at other local clubs, notably Straight Blast Gym Ireland, where he was coached by John Kavanagh.

Concerned about their son’s chances of making a career as an athlete, McGregor’s parents persuaded him to train as a plumber after he completed secondary school. He worked as a plumber’s apprentice for one year before quitting to focus on MMA full-time, convinced that he had what it took to become a champion.

Professional MMA career

In 2008 McGregor began competing on the professional MMA circuit in the lightweight and featherweight divisions. Over the next four years he lost only two professional fights. In 2011 he defeated an opponent by knockout within four seconds. During this time he survived on his prize earnings and unemployment benefits, receiving emotional support from his family and from his girlfriend, Dee Devlin, whom he began dating shortly after quitting his plumbing job.

In June 2012 McGregor won the Cage Warriors Fighting Championship (CWFC) in the featherweight division. Six months later he became the CWFC lightweight champion. McGregor’s success combined with his cockiness made him a fast-rising star in MMA. Among his arsenal of strengths are his use of distance and range, his formidable striking accuracy, and his powerful left hand. By February 2013 he had caught the eye of Dana White, president of the UFC, the largest promotion company in the sport. White signed McGregor that same month. In April McGregor fought his first UFC match, against Marcus Brimage; he won by technical knockout in the first round in a bout that lasted 1 minute 7 seconds.

McGregor’s winning streak continued, despite tearing his anterior cruciate ligament (ACL) in his left knee in a fight in 2013. In July 2015 he clinched his first UFC championship in a fight against Chad Mendes in Las Vegas. The much-hyped event included an appearance by the singer Sinéad O’Connor, who performed “The Foggy Dew” (an Irish rebel song) as McGregor’s entrance music. McGregor defeated Mendes by technical knockout in the second round to become the UFC interim featherweight champion. In December he won the UFC featherweight championship with a sensational left-hook knockout of opponent José Aldo in a match that lasted all of 13 seconds.

In 2016 McGregor had his first professional loss, tapping out in the second round of a welterweight division match against Nate Diaz. The lead-up to the match was rancorous; the two fighters traded insults and came to blows during a news conference two days before the fight. He and Diaz faced off again five months later, in August. This time McGregor was victorious in a five-minute fight that he won by majority decision. In November he fought Eddie Alvarez for the UFC lightweight championship, which he won in the second round by knockout. The win made McGregor the first UFC champion to simultaneously hold titles in two weight divisions.

In August 2017 McGregor ventured outside the discipline of MMA by participating in a boxing match against legendary fighter Floyd Mayweather, Jr. The bout was preceded by a large promotional campaign and a great deal of trash talk between the two competitors, though there was a note of knowing showmanship and camaraderie in the verbal sparring. Mayweather won the fight by technical knockout in the 10th round, although commentators praised the underdog McGregor for making the bout competitive. Both men reportedly walked away with millions; McGregor’s take was estimated to be $130 million.

After being stripped of his UFC championship titles because of fight inactivity, McGregor returned to the UFC cage in 2018 in a fight for the lightweight championship with Khabib Nurmagomedov. Before the fight, McGregor persisted with his outrageous “Notorious” persona, riling up Nurmagomedov—a Muslim from Dagestan republic, Russia—with offensive comments about his opponent’s culture and religion. The beef became so intense that, immediately after McGregor tapped out in the fourth round, Nurmagomedov leaped out of the cage into the audience, sparking a brawl between the rivals’ supporters.

McGregor announced his retirement as a fighter in 2019, with a record of 21–4 at the time. But it was short-lived, and in 2020 he faced off against Donald (“Cowboy”) Cerrone in a welterweight division match. He won by knockout in 40 seconds using a battery of shoulder strikes and a head kick. A more focused McGregor seemed to have toned down the most outlandish aspects of his fighting persona, mostly laying off the verbal insults and psychological warfare that had helped to make him infamous. That same year he again claimed that he was retiring, but he returned in 2021 for two fights against Dustin Poirier, both of which he lost. The second fight was stopped by a doctor’s order after McGregor broke his tibia. After spending several years recovering from his leg injury and ostensibly preparing for his next fight, McGregor finally agreed to return to the UFC in 2024, to face Michael Chandler. However, the fight was canceled a few weeks before its scheduled date of June 29, reportedly because McGregor was injured.

Controversies

McGregor’s ascent in MMA initially made him a hero in his native Ireland and to fans around the world. His success spurred a surge of interest in MMA, a sport once repudiated by mainstream audiences and sponsors because of its violence. His brash persona soon seemed to get the best of him, however, as he increasingly fell afoul of the law. His contentious relationship with Nurmagomedov boiled over in April 2018 when McGregor and a group of friends traveled all the way from Ireland to Brooklyn to ambush Nurmagomedov at a UFC publicity event. McGregor and his friends attacked a UFC bus carrying his adversary and other fighters, and McGregor threw a metal dolly at the bus, shattering a window and injuring two fighters. He was ultimately charged with disorderly conduct and ordered to perform community service and attend anger management courses.

McGregor has also been accused numerous times of sexual and physical assault, including an incident that was caught on camera in 2019 in which he punched an older man in a Dublin pub after the man refused to try McGregor’s brand of whiskey. McGregor publicly expressed remorse for the assault, pleaded guilty in court, and was made to pay a fine.

Although a number of his assault cases were dropped, a sexual assault case filed by a woman in Dublin in 2018 remains ongoing. McGregor was investigated by Irish police in 2019 and was not charged. In 2021 the woman in the case filed a civil lawsuit against him, alleging personal injury. The case was expected to be heard by a jury in Ireland in November 2024.

In addition, McGregor stoked controversy through his posts on Twitter (now X) regarding Irish politics, particularly on the fraught topic of immigration and his seeming support for right-wing, xenophobic groups.

Business ventures and personal life

In 2018 McGregor launched Proper No. Twelve whiskey. In 2021 Forbes listed McGregor as the world’s highest paid athlete of 2020, estimating that he had earned $180 million, $150 million of which was the result of McGregor selling his majority stake in the whiskey company. His other business projects include appearing in advertisements for numerous brands, opening the Black Forge Inn in Dublin, and developing the McGregor FAST fitness training method.

McGregor has four children with his longtime partner, Dee Devlin, to whom he became engaged in 2020. He has served as a coach on The Ultimate Fighter reality television show, and in 2024 he made his film acting debut in Road House, a remake of the 1989 cult classic that starred Patrick Swayze. McGregor plays a bad guy who squares off against Jake Gyllenhaal’s character, an ex-UFC fighter and bouncer.
