Jon Jones was 23 years old when he became UFC champion. That record has survived since 2011.
Plenty of brilliant young fighters have come through the promotion since then, but nobody has quite caught him. Joshua Van got closest in December 2025, winning flyweight gold at 24 years and 57 days old.
The difference between them was less than a year.
That might not sound like much, but reaching a UFC title fight before your 24th birthday is incredibly difficult. Most fighters are still building their record at that age, never mind preparing to face the best in the world.

Who Is the Youngest UFC Champion Ever?
The record belongs to Jon Jones.
He beat Mauricio Rua at UFC 128 on 19 March 2011 and became light heavyweight champion at 23 years and 243 days old. UFC still recognises Jones as its youngest champion, with current flyweight champion Joshua Van second at 24 years and 57 days.
The five youngest UFC champions are:
- Jon Jones: 23 years, 243 days
- Joshua Van: 24 years, 57 days
- Jose Aldo: 24 years, 72 days
- Josh Barnett: 24 years, 132 days
- Carlos Newton: 24 years, 260 days
What is interesting is how different those five championship stories actually were.
Jon Jones Set the Record Almost by Accident
Jones was not originally meant to challenge Rua.
He fought Ryan Bader at UFC 126 in February 2011, submitted him, then learned inside the Octagon that an injured Rashad Evans could no longer face Rua.
Jones was offered the title fight instead. Six weeks later, he was champion.
There was no nervous 23-year-old performance either. Jones overwhelmed Rua and stopped him in the third round. UFC described the victory at the time as confirmation that Jones was something genuinely unusual, and history has been fairly kind to that assessment.
The record could easily have been one of those strange statistics attached to a fighter whose career never quite lived up to the hype. Instead, Jones kept winning.
He went through Quinton Jackson, Lyoto Machida, Rashad Evans, Vitor Belfort and Alexander Gustafsson, among others. The youngest champion record ended up being the first line in a much longer story.

Joshua Van Came Within Eight Months
This is where the record has become relevant again.
Joshua Van joined the UFC in June 2023. Just two and a half years later, he was flyweight champion.
He won the title from Alexandre Pantoja at UFC 323, although the finish was an unusual one. Pantoja injured his elbow after 26 seconds and could not continue, leaving Van champion at 24 years and 57 days old.
UFC now officially lists him as the second-youngest champion in its history.
There was naturally some awkwardness around the way he had won it. A belt is a belt, but nobody wants their championship moment to arrive because an opponent gets injured seconds into the fight. Van’s first defence helped.
He faced Tatsuro Taira in May 2026 and stopped him in the fifth round. No freak injury. No argument about whether he had really proved himself as champion.
Now Pantoja gets another crack at him.

Van cannot beat Jones’ age record anymore. What he can do is take advantage of winning the belt so early. At 24, he has time on his side.
Jose Aldo Is the Odd One Out
Aldo sits only 15 days behind Van on this list, although he got there differently. There was no UFC title fight.
When the WEC was folded into the UFC in 2010, Aldo was already its featherweight champion and clearly the best fighter in the division. The UFC simply installed him as its inaugural 145lb champion. He was 24 years and 72 days old.
That makes Aldo an unusual entry because he was awarded the UFC belt rather than winning it inside the Octagon. He had certainly earned his status elsewhere, though. Aldo went 8-0 in the WEC and had already defended its title twice.
Once he arrived in the UFC, he proved there was nothing ceremonial about the championship. Aldo defended it seven times.
Mark Hominick, Frankie Edgar, Chad Mendes and Chan Sung Jung were among the fighters who tried and failed to move him from the top.
His reign also helped establish featherweight as one of the promotion’s major divisions. Our UFC weight classes guide explains how the 145lb division fits into the current UFC structure.
Before Jones, Josh Barnett Had the Record
This one goes back to a very different UFC.
Josh Barnett was 24 when he fought Randy Couture for the heavyweight championship at UFC 36 in March 2002. Couture was 38.
Barnett stopped him in the second round and, at 24 years and 132 days, became the youngest champion the promotion had seen. UFC confirms that the record remained his until Jones broke it almost nine years later.
What followed was considerably messier. Barnett later tested positive for banned substances, was stripped of the championship and left the promotion.
So while Jones turned his record-breaking night into the start of a huge title reign, Barnett never even made a successful defence.
Same achievement. Completely different aftermath.
Carlos Newton Quietly Completes the Top Five
Carlos Newton tends to get forgotten in discussions like this. He shouldn’t.
At UFC 31 in 2001, Newton challenged Pat Miletich for the welterweight championship. Miletich had been champion for years and had already defended the belt four times.
Newton submitted him. He was 24 years and 260 days old.
His reign lasted only until his next fight, when Matt Hughes took the title in one of the strangest finishes the UFC has ever produced.
Hughes was trapped in Newton’s triangle choke and lifted him into the air. He then slammed Newton onto the canvas, knocking him out and winning the championship.
Newton’s time at the top was brief, but his age record has lasted. Even after Van entered the list in 2025, Newton remains one of only five UFC champions to have held gold before turning 25.
What About Max Holloway and Georges St-Pierre?
They were close. Max Holloway was 25 when he stopped Jose Aldo to become undisputed featherweight champion in 2017.
Georges St-Pierre was also 25 when he first won UFC gold, beating Matt Hughes for the welterweight title.
Cody Garbrandt, Rose Namajunas, Frank Mir and BJ Penn are other examples of fighters who reached championship level unusually early.
None, however, managed it before their 25th birthday. That is what separates the top five.
Will Anyone Break Jon Jones’ Record?
Probably, eventually. But Van’s rise shows how much needs to happen in a very small window.
A fighter has to turn professional young, reach the UFC quickly, start beating ranked opponents almost immediately and then somehow find themselves in a title fight before they turn 23 years and 243 days old.
A single loss can push the whole thing back a year or two. So can an injury.
Jones needed some luck with the timing too. Rashad Evans pulling out of the Rua fight opened a title opportunity earlier than expected, and Jones was good enough to take it.
More than 15 years later, that combination has not happened again. Van got closer than anyone, but Jones still owns the record.
