Conor McGregor

Conor Anthony McGregor is an Irish professional mixed martial artist and businessman. He is the biggest pay-per-view draw in MMA history, having headlined the five highest-selling UFC events. McGregor became the first UFC fighter to hold championships in two weight classes simultaneously when he won the featherweight and lightweight titles in 2015 and 2016.

Known for his brash confidence and striking precision, McGregor knocked out Jose Aldo in 13 seconds at UFC 194, the fastest finish in a UFC title fight. His 2017 boxing match against Floyd Mayweather Jr. generated over 5.3 million PPV buys, the second highest in history. In 2021, Forbes ranked him the world's highest-paid athlete at $180 million, largely from selling his Proper No. Twelve whiskey stake.

Outside the cage, McGregor has built a business empire including the Black Forge Inn pub and Forged Irish Stout, and he co-owns the Bare Knuckle Fighting Championship. His career has been marked by both historic achievements and significant legal controversies, including a 2024 civil court ruling that he assaulted a woman in 2018. In 2025, he briefly ran for Irish president before withdrawing. [edit]

McGregor grew up in Crumlin, a working-class suburb of Dublin, the youngest of three children. At age 12, he joined Crumlin Boxing Club under coach Phillip Sutcliffe, winning a Dublin Novice Championship. He boxed until age 17 before transitioning to mixed martial arts under John Kavanagh at Straight Blast Gym Ireland.

He attended Irish-language schools, including Gaelscoil Scoil Mologa and Gaelcholáiste Coláiste de hÍde in Tallaght, where he played soccer. After leaving school, he worked as an apprentice plumber but quit over his parents' objections to pursue fighting full-time. In 2008, he made his professional MMA debut, fighting in local promotions before joining Cage Warriors. [edit]

McGregor won the CWFC Featherweight and Lightweight Championships in 2012, then signed with the UFC in 2013. He quickly rose through the ranks with five straight wins, earning a title shot. At UFC 189 in July 2015, he defeated Chad Mendes to win the interim featherweight title. Five months later at UFC 194, he knocked out Jose Aldo in 13 seconds to become undisputed champion.

In November 2016, he moved up to lightweight and stopped Eddie Alvarez at UFC 205, making history as the first simultaneous two-division UFC champion. He then took a boxing superfight against Floyd Mayweather Jr. in August 2017, losing by TKO in the 10th round but earning an estimated $100 million. Returning to MMA, he lost to Khabib Nurmagomedov at UFC 229 in a grudge match that set the MMA PPV record with 2.4 million buys.

After a brief retirement, he returned in January 2020 to knock out Donald Cerrone in 40 seconds. His last fight came in July 2021 against Dustin Poirier, where he suffered a broken tibia in the first round. Since then, he has focused on his businesses and has not competed. [edit]

McGregor's public persona is defined by his brash confidence, flashy suits, and theatrical walkouts draped in the Irish tricolour. He is the most-followed UFC fighter on social media, with over 70 million followers across platforms. Fans are drawn to his trash-talking bravado and knockout power, but critics point to his legal troubles and inflammatory political statements. His social media voice is provocative, often stirring controversy on Irish politics and immigration. His nickname "Notorious" reflects his self-promotional style that helped bring MMA into the mainstream. [edit]

Conor McGregor stands as the 192nd most famous person in the world, a position he has held steady through cycles of global attention. His standing is even more dominant within his home nation, where he ranks as the 1st most famous person from Ireland, and he claims the 4th most famous person in MMA & Boxing. These placements on the iFANN Global Fame Rankings reflect a career built on historic achievements and a persona that transcends the sport itself.

While there is no single officially designated name for his supporters, the community identifies simply as "McGregor fans" or aligns with the broader "Irish MMA" circle. This group is defined by intense loyalty and a strong nationalistic element, often rallying behind him as a symbol of modern Ireland's resurgence on the global stage. Fans frequently view purchasing products like his "Proper No. Twelve" whiskey brand as acts of solidarity, extending their support well beyond the octagon. The organization of this fanbase remains largely organic and driven by social media rather than formal clubs, with notable campaigns including massive birthday celebrations on July 14th where followers flood platforms with tributes and organize charity drives in his name.

His interaction with this audience is direct and provocative, with McGregor often addressing his followers as "the people" or "the family." This connection blurs the line between public figure and community member, especially when he invites fans into training camp events. Legends surrounding his career remain central to this mythology, anchored by verified moments like his 13-second knockout of José Aldo at UFC 194, which illustrated his psychological dominance. Other stories, such as the chaotic press conference brawl with Khabib Nurmagomedov, are retold as defining chapters of his mythos. Recent narratives have added layers to his legacy, featuring his role as a predictor for upcoming major bouts like UFC 330 and his mentorship of younger Irish fighters, creating a lineage of Irish dominance that fans eagerly anticipate.[edit]

Conor Anthony McGregor was born in Dublin but carries a unique heritage; his father Tony was born in Liverpool to an English mother and Irish father. Before stepping into the octagon, McGregor worked as a plumber's apprentice and attended Irish-language schools throughout his education. His career is marked by historic achievements, including becoming the first UFC fighter to hold two titles simultaneously and delivering the fastest finish in a UFC title fight history against Jose Aldo in just 13 seconds.

His life outside the cage has been equally eventful and controversial. He has faced over 20 criminal charges involving driving offenses and assault, and his public persona often sparks debate regarding his political statements on immigration. In a moment that blurred the lines between performance and reality, he performed a skit at Game 4 of the 2023 NBA Finals where he knocked out the Miami Heat mascot, sending the performer to the emergency room.

Legends of his career include the viral explosion of his left hand on Aldo, a moment so sudden it became a defining instant in sports history. Another iconic story is the chaotic press conference brawl with Khabib Nurmagomedov, which escalated into a cage intrusion and resulted in lifetime bans for both fighters. Fans still retell these stories as central pillars of his mythos, alongside his recent role as a predictor for upcoming major bouts like UFC 330.[edit]

McGregor was born to Tony McGregor, a taxi driver originally from Liverpool, and Margaret McGregor, a laundry worker. He is the youngest of three children, with an older brother and sister. His cousins include footballer Keith Buckley and Warren Davis. McGregor married his long-time partner Dee Devlin in 2025; they have four children together: Conor Jr. (born 2017), Croia (born 2019), Rian (born 2021), and a fourth child. The family lives in Dublin, where McGregor owns the Black Forge Inn pub. [edit]

McGregor trains under John Kavanagh at Straight Blast Gym Ireland. He has fought elite opponents including Floyd Mayweather Jr., Khabib Nurmagomedov, Nate Diaz, Dustin Poirier, and Jose Aldo. His wife Dee Devlin has been with him since before his UFC career. [edit]

McGregor's only known public relationship has been with Dee Devlin. They began dating around 2008, before his UFC career, and she supported him financially during his early fighting days. The couple got engaged in 2020 and married in 2025. They have four children together: Conor Jr. (born 2017), Croia (born 2019), Rian (born 2021), and a fourth child. As of 2026, McGregor is married to Devlin and they remain together. [edit]

As of 2026, iFANN currently estimates Conor McGregor's net worth at $200 Million. This substantial figure is anchored by the 2021 sale of his majority stake in Proper No. Twelve Irish Whiskey, which generated approximately $150 million. His fighting career contributed significantly to this total, with earnings reaching $100 million from the Mayweather boxing match alone, supplemented by millions in UFC PPV points.

Beyond fighting and spirits, McGregor owns the Black Forge Inn pub in Dublin, co-owns the Bare Knuckle Fighting Championship, and operates ventures including Forged Irish Stout, McGregor FAST fitness, TIDL Recovery Spray, and the Dystopia video game series. His wealth peaked in 2021 when Forbes named him the highest-paid athlete globally. However, a November 2024 Irish High Court ruling found him liable for assaulting a woman, leading to the loss of endorsements with brands like Reebok and Burger King. He was ordered to pay over €248,000 in damages and approximately €1.5 million in legal costs. Despite these financial setbacks, his whiskey sale and diverse business holdings maintain his net worth at a significant level.[edit]

McGregor won the UFC Featherweight Championship in 2015 by knocking out Jose Aldo, and the UFC Lightweight Championship in 2016 by defeating Eddie Alvarez. He also held the CWFC Featherweight and Lightweight Championships simultaneously in 2012. His 13-second knockout of Aldo remains the fastest finish in UFC title fight history. [edit]
