Conor McGregor Age 2026: How Old Is Conor McGregor?

Conor McGregor is 38 years old in November 2026. He was born on July 14, 1988, in Crumlin, Dublin, Ireland, and turned 38 on July 14, 2026 — just three days after his long-awaited UFC return at UFC 329 ended in a 69-second knee injury against Max Holloway. At 38, the former two-division UFC champion is the richest fighter in mixed martial arts history, with an estimated fortune of $200–230 million anchored at $200 million, and he is planning one last Octagon appearance in the summer of 2027, when he will be 39.

The age question follows McGregor everywhere because his career has been a race against the clock. He debuted in the UFC at 24, won his first world title at 27, became the sport’s first simultaneous two-division champion at 28, crossed over to box Floyd Mayweather at 29, and then spent most of his thirties away from the cage — five years between fights before the July 2026 comeback. This page settles the number with dated sources, walks through his age at every career milestone, and explains what 38 means for a fighter who says he has one fight left.

Quick Facts: Conor McGregor at a Glance

How Old Is Conor McGregor in 2026?

Conor McGregor is 38 years old. He was born on July 14, 1988, which means he spent the first half of 2026 as a 37-year-old and turned 38 in the middle of July — three days after the biggest fight of his late career. The maths is simple, but the number lands differently depending on when you ask: search results written in the spring of 2026 still called him 37, because he had not yet had his birthday. Any page that calls him 37 after July 14, 2026 is out of date.

Wikipedia lists his birth date as July 14, 1988, and gives his age as 38. The UFC’s own fighter database, the fight records kept by Tapology and Sherdog, and every major outlet covering his July 2026 return — Athlon Sports, Sportskeeda, Bloody Elbow, MMA Fighting — all describe him as 38. As of November 10, 2026, he is 38 years and just under four months old.

Why does the number matter so much for this fighter? Because in mixed martial arts, 38 is the age where the conversation changes. Most champions peak between 28 and 33. McGregor’s great rival Khabib Nurmagomedov retired at 32. The man who beat McGregor at UFC 229 walked away undefeated and never came back. McGregor, by contrast, is still talking about fighting at 39 — and the sport is still listening, because no fighter in UFC history has sold more pay-per-views.

When Is Conor McGregor’s Birthday?

Conor McGregor’s birthday is July 14. He was born in 1988, which makes him a Cancer by zodiac sign and places his birth in the Chinese Year of the Dragon — a detail his fans enjoy, given how much of his persona leans on fire, luck and showmanship. His birthday has become a small event in the MMA calendar: in 2026 it fell three days after UFC 329, so instead of a celebration he spent it starting the long recovery from a torn ACL and meniscus.

Birthdays have tracked his career in an almost poetic way. He turned 25 the week he fought Max Holloway for the first time in August 2013 — and tore the ACL in his left knee in that fight. He turned 28 in July 2016, four months before he beat Eddie Alvarez at UFC 205 to become the first fighter to hold two UFC belts at once. He turned 33 in July 2021, three days after Dustin Poirier beat him at UFC 264 and he broke his leg. And he turned 38 in July 2026, three days after the Holloway rematch ended his comeback in 69 seconds. July has never been a quiet month for McGregor.

His 39th birthday, July 14, 2027, is now the date to watch. International Fight Week — the UFC’s annual summer showcase in Las Vegas — traditionally falls in early July, and McGregor has said he wants his final UFC fight on that card. If the timing holds, he would walk out as a 38-year-old and walk away, one fight later, as a 39-year-old heading for bare-knuckle boxing.

Conor McGregor’s Age at Every Career Milestone

One reason the age question keeps getting asked is that McGregor packed a whole career into a very short window — then spent years away from it. Here is how old he was at each turning point, with dates from the UFC’s official records and contemporary reporting.

The pattern is hard to miss. Everything that made McGregor a global star — the titles, the Mayweather fight, the whiskey launch — happened between the ages of 27 and 30. Everything since has been shaped by absence: injuries, long layoffs, court cases and business deals. He has fought just four times since turning 30, and lost three of them. The 2026 return was supposed to reset that story. Instead, at 38, it added a new injury to the list.

Still, the timeline cuts both ways. Fighters who stay active into their late thirties usually do it by fighting smarter — picking their spots, leaning on experience, and accepting that the reflexes of 27 are gone. McGregor’s game was always built on timing and distance rather than raw athleticism, which is exactly the kind of style that can age well. The question is whether his body will let him prove it.

Growing Up in Crumlin: The Dublin Years

Conor Anthony McGregor was born in Crumlin, a working-class district on the south side of Dublin, and raised there by his parents Tony and Margaret McGregor. Crumlin in the late 1980s and 1990s was the kind of neighbourhood where boxing gyms did real social work, and McGregor walked into Crumlin Boxing Club at 12 — an age when most kids are still deciding which sport they like. He stayed with boxing through his teens, and the footwork and head movement he learned there became the base of everything that followed.

School did not hold him. He left education early and trained as a plumber, working as an apprentice while he trained in his spare hours. The plumbing job is now part of the legend — the working-class kid who traded wrenches for wraps — but at the time it was simply what young men in Crumlin did. He has said in interviews that he hated the apprenticeship and knew, even then, that fighting was the only thing he wanted to do with his life.

The turn came when he was 17 or 18, after meeting Tom Egan and then, through him, the coach who would shape his career: John Kavanagh at Straight Blast Gym (SBG) Ireland. Kavanagh saw a raw, gifted striker with unusual movement and began building a mixed martial artist around him. McGregor turned professional in February 2008, at 19, and fought on the small Irish and British circuits for five years, losing twice early — to Artemij Sitenkov by submission in his second pro fight, and to Joseph Duffy in 2010 — before the run that changed everything.

By 2012, at 23, he was the Cage Warriors featherweight and lightweight champion at the same time, the first European fighter to hold two titles in that promotion at once. The UFC signed him in early 2013. He was 24, broke, living on social welfare in Dublin, and telling anyone who would listen that he was going to be the biggest star the sport had ever seen. Within three years, he was.

The full life story — from Crumlin to the double championship, the whiskey deal and the family — is told at greater length in Conor McGregor’s biography on GuideNetWorth, which covers the same journey from a different angle. What matters here is the clock: he reached the top of the sport at 27 and 28, younger than almost every champion who has held two belts.

The Rise: From Plumber’s Apprentice to UFC Double Champion

McGregor’s UFC debut came on April 6, 2013, against Marcus Brimage in Stockholm. He was 24. He knocked Brimage out in 67 seconds, collected a Knockout of the Night bonus, and used the post-fight interview to announce himself to the world. Four months later, at 25, he beat a young Max Holloway by unanimous decision in Boston — a win that cost him dearly, because he tore the anterior cruciate ligament in his left knee during the fight and spent the next ten months out of the cage.

The layoff could have stalled him. Instead, he came back in July 2014 and went on a run that remains one of the great hot streaks in UFC history: stoppages of Diego Brandao, Dustin Poirier, Dennis Siver and Chad Mendes, then the 13-second knockout of Jose Aldo at UFC 194 on December 12, 2015, to win the featherweight title. He was 27, and the punch that ended Aldo’s decade-long unbeaten run is still shown in highlight reels today.

Eleven months later, at 28, he beat Eddie Alvarez at UFC 205 in New York to win the lightweight title, becoming the first fighter in UFC history to hold championships in two weight classes at the same time. He never defended either belt — the UFC stripped him of the featherweight title weeks later and the lightweight title in 2018 — but the achievement stands, and no one has matched it since. For a full picture of how he measures up physically against his rivals, see our Conor McGregor height profile, which puts his 5 ft 9 in frame and 74-inch reach against the UFC’s official numbers.

What followed was the Mayweather fight. In August 2017, at 29, McGregor crossed over into professional boxing to face Floyd Mayweather Jr. in Las Vegas. He lost by tenth-round stoppage, as almost everyone expected, but he told Forbes he made about $100 million from the night, and the event sold around 4.3 million pay-per-views in North America — the second-biggest boxing pay-per-view ever. It made him rich beyond anything the UFC alone could have done, and it changed what he wanted from fighting. After Mayweather, he fought for money and legacy, not for the next rung on the ladder.

The years after the Mayweather fight were harder. He lost to Khabib Nurmagomedov at UFC 229 in October 2018, at 30, in the biggest pay-per-view in UFC history. He beat Donald Cerrone in 40 seconds in January 2020, at 31 — his last win to date. Then came two losses to Dustin Poirier in 2021, the second of which ended with a broken left leg at UFC 264 in July 2021, when he was 32. He was supposed to return against Michael Chandler in June 2024 and withdrew with a broken toe. The comeback kept slipping — until July 2026.

The 2026 Comeback: UFC 329 and the Knee Injury

On July 11, 2026, at 37 years old and three days short of his 38th birthday, Conor McGregor walked back into the Octagon for the first time in nearly five years. The event was UFC 329 at the T-Mobile Arena in Las Vegas. The opponent was Max Holloway — the same man he had beaten as a 25-year-old in 2013, now a former featherweight champion himself, and the fight was at welterweight, a division neither man had made his name in. The build-up was enormous. The fight lasted 69 seconds.

McGregor opened with a jumping kick, his first strike of the night. He landed it — and his right knee gave way as he came down. Holloway was awarded a technical knockout win at 1:09 of the first round, per UFC.com, without having to do much of anything. McGregor later confirmed the damage himself on X: a torn ACL and meniscus in his right knee. As he put it, it was the same injury as the first Holloway fight, only this time in the opposite leg.

The symmetry was brutal. In 2013, at 25, he tore his left ACL beating Holloway and fought on to win the decision. In 2026, at 37, he tore his right ACL and meniscus against the same man and could not continue. He announced on August 5, 2026 that he had undergone surgery, and he has since said his recovery will take nine to 12 months — and that this time he plans to use all of it. In September he admitted he had come back too early from the first ACL tear and had been fighting, in his own words, on one leg.

Three months after the injury, on October 11, 2026, he posted what outlets described as a sparring image to his Instagram Stories, the first public sign that the rehab was moving. The swelling was down, he said, and he was off the crutch within two or three weeks. But the timeline he has set for himself is patient: cleared at nine months at the earliest, fighting again in the summer of 2027. UFC chief executive Dana White has offered a similar, slightly more cautious timeline, saying McGregor is effectively out for a year. As of November 2026, there is no official next fight — no contract announced, no date confirmed, no opponent named by the UFC.

For the record books, the loss leaves McGregor at 22-7, on a three-fight losing run, without a win since the Cerrone stoppage in January 2020. It also leaves the Holloway series tied at 1-1, with a knee wrecked in both meetings. That tie is the thread McGregor himself keeps pulling at.

What Comes Next: The 2027 Farewell Plan

McGregor has been unusually clear about what he wants next. He says he has one fight left on his UFC contract — a claim the UFC has not publicly confirmed — and he wants to spend it on Max Holloway, in a trilogy fight, at International Fight Week in July 2027. MMA Fighting has reported that he is targeting that date, and Holloway has said he would be open to a third meeting, though the UFC has announced nothing.

Then came the twist. On November 3, 2026, appearing ringside at a Hype FC card in Rome, McGregor spelled out how his UFC run ends — and it is not with retirement. He said he will lay down his gloves in the Octagon for his final UFC contract fight, “but not to retire, to announce bareknuckle.” The landing spot is obvious: he became a co-owner of Bare Knuckle Fighting Championship in 2024, and a move into bare-knuckle boxing after his UFC deal ends has been rumoured for two years. At 38, with one fight left and a repaired knee, he is planning a second act in a sport with no gloves and no takedowns.

He will be 39 during the summer of 2027. If the Holloway trilogy happens on International Fight Week, it would be his farewell to the Octagon at an age when almost every great lightweight before him had already left. Whether the UFC agrees to the date, the opponent and the send-off is another matter — White has said he will not talk about McGregor’s next fight until he is given the all-clear to return. For now, the plan exists only in McGregor’s words. But McGregor’s words have a habit of becoming the UFC’s plans.

How McGregor’s Age Compares to His UFC Peers

Thirty-eight sounds old for a fighter until you look at the men around him. The lightweight and welterweight divisions McGregor has fought in are full of veterans, and several of his rivals are older than he is — or were older when they did their best work.

The comparison that stings most is Khabib. Born just two months after McGregor, in September 1988, Nurmagomedov retired at 32 with a 29-0 record and never looked back. McGregor, at the same age, was already four years into a run of losses and long layoffs. The two men had the same clock and used it very differently. You can read more about the rivalry in our profile of Khabib Nurmagomedov’s height and career — the Dagestani’s measurements and record sit alongside McGregor’s in the same series.

The comparison that gives McGregor hope is Jon Jones. Born in July 1987, Jones is a year older than McGregor and was still winning heavyweight title fights in his late thirties. His story shows that an elite fighter with a style built on timing, reach and fight IQ can stay at the top well past 35. Read Jon Jones’s biography for the full picture of how the sport’s greatest heavyweight managed his late career.

And then there is Nate Diaz, 41, who fought McGregor twice in 2016 — winning the first, losing the rematch — and who is still headlining boxing events in his forties. Diaz proves that a McGregor-era rival can keep drawing crowds long after his championship years. The difference is that Diaz stayed active. McGregor’s problem at 38 is not his age in isolation; it is his age plus five years of rust, three straight losses, and a knee that has now failed him twice. Age is a number. Inactivity is the thing that makes the number matter.

Two more names from our own pages round out the picture. Israel Adesanya’s biography covers a fellow striker who hit the top in his early thirties and is now navigating his late thirties in the same sport, while Jake Paul’s net worth profile tracks the 29-year-old crossover star who has spent years calling McGregor out — a fight that would pair a 38-year-old legend with a 29-year-old YouTuber-turned-boxer, and one the numbers suggest both men would love.

The Money at 38: How the Fortune Was Built

Age matters to McGregor’s bank account too, because almost all of his fortune was made before he turned 33. His estimated net worth in 2026 is $200–230 million, anchored at $200 million — the figure used by Parade in January 2026 and by The Sun’s SunSport desk (£150 million, roughly $200 million) in July 2026, with BetMGM’s $230 million as the credible high mark. Celebrity Net Worth also lists $200 million. He has never disclosed his finances publicly, so every number here is an independent estimate, and the range reflects honest disagreement about how much of his gross earnings he kept after taxes, spending and legal costs.

Two paydays built the fortune. The first was the Mayweather fight in August 2017, when he was 29: he told Forbes he made about $100 million from the night. The second was the sale of Proper No. Twelve Irish whiskey. He launched the brand in 2018, at 30. In mid-2020, Proximo Spirits — the drinks company behind Jose Cuervo — paid $250 million to raise its stake from 20% to 49%. In April 2021, McGregor and his partners Ken Austin and Audie Attar sold their remaining 51% stake in a deal valued at up to $600 million in total, including the earlier $250 million. The headline number misleads: it was split three ways, and part of it depended on performance targets. Forbes put McGregor’s personal cut at about $150 million; the Irish Independent reported $130 million. The honest range is $130–150 million — still the single biggest contributor to his fortune.

A footnote from 2026: Artem Lobov, McGregor’s former training partner, sued in 2022 claiming a handshake deal entitled him to 5% of the whiskey sale. The case settled on April 15, 2026, with terms undisclosed, per The Daily Pour and RTE. The settlement closed the last open dispute over the whiskey money.

The rest of the fortune comes from UFC purses and pay-per-view points across a career that includes the biggest-selling event in UFC history (UFC 229, October 2018), endorsements with brands including Reebok, Monster Energy and Beats, an acting role in the 2024 remake of Road House, and his newer ventures: Forged Irish Stout, the Black Forge Inn pub in Dublin, August McGregor menswear, Notorious Cigars, and his 2024 stake in Bare Knuckle Fighting Championship. None of those has reported figures large enough to move the estimate on its own. Our sister site has the full breakdown — Conor McGregor’s net worth on NetWorthCraft walks through every verified dollar behind the $200 million figure, from the fight purses to the whiskey deal structure.

What is striking at 38 is how little of the fortune depends on fighting any more. McGregor earned roughly $43 million in Forbes’ 2022 window, the year after the whiskey windfall dropped out of the numbers, and his income since has come mostly from business and endorsements. That is why the 2027 plan makes financial sense even if the fighting part does not: one last UFC payday, then a bare-knuckle career in a promotion he partly owns. At 38, he is no longer fighting to get rich. He is fighting because he does not know how to stop.

Personal Life: Dee Devlin and the Kids

McGregor has been with his partner Dee Devlin since 2008 — since before he was famous, before the UFC, back when he was a plumber’s apprentice training at SBG and living on welfare. Devlin supported him through the broke years, and she has been at the centre of his public life ever since: ringside at his fights, in the front row of the Mayweather build-up, and running much of the family business behind the scenes. They have four children together: Conor Jr., born in 2017; Croia, born in 2019; Rían, born in 2021; and Mack, born in 2023.

His 38th year has been a family year as much as a fighting year. He spent the summer of 2026 recovering from knee surgery at home in Ireland, and his social media through the autumn has been a mix of rehab updates and family posts. The children are still young — the eldest is nine — which is one more reason the 2027 timeline matters: a final fight at 39, then a second career in bare-knuckle boxing, would let him stay in the sport he loves without the year-round grind of a UFC training camp.

Devlin’s role is worth noting because it explains how McGregor’s life has stayed stable while his career has lurched from one crisis to the next. She has been with him since he was 19 and she was working to keep them afloat while he trained. Whatever the next three years bring — a farewell fight, a bare-knuckle run, more business deals — the family setup that carried him from Crumlin to the top of the sport is unchanged.

Controversies and Legal Trouble

No honest profile of McGregor at 38 can skip this section, because the legal trouble has shaped his thirties as much as the fighting has. The incidents are a matter of public record, and they are worth stating plainly.

In April 2018, at 29, he attacked a bus carrying UFC fighters at the Barclays Center in Brooklyn, throwing a metal dolly through a window and injuring two fighters. He later pleaded guilty to disorderly conduct and was sentenced to community service and anger management classes. In 2019 he pleaded guilty to assault after punching a man in a Dublin pub and was fined €1,000.

The most serious case came in November 2024, when a civil jury at the High Court in Dublin found McGregor liable for assaulting Nikita Hand in a Dublin hotel in December 2018 and awarded her damages of almost €250,000. McGregor denied the allegation and has appealed. The verdict, which was reported around the world, cost him endorsement deals and damaged his standing in Ireland, where he had once been a folk hero.

These cases matter to the age story because they fill the years when he was not fighting. Between his last win in January 2020 and his return in July 2026, McGregor fought three times and lost all three — and spent much of the rest of the time in courtrooms, in business meetings, and in the headlines for reasons that had nothing to do with the Octagon. At 38, the question is not only whether his knee will hold up, but whether the public still wants to watch him try.
