Mixed Martial Arts has transformed from a niche spectacle into one of the most watched sports on earth. The UFC has produced fighters who are genuine global superstars, recognised from Rio to Tokyo, Dublin to Las Vegas. But who are the most famous MMA fighters of all time? We rank the 10 biggest names in the sport’s history, weighing championship reigns, global profile, pay-per-view records, and their impact on the growth of MMA worldwide.
1. Conor McGregor — The Biggest Star MMA Has Ever Seen
Conor McGregor is without question the most famous MMA fighter who has ever lived. The Irish superstar became the first fighter in UFC history to hold two championship belts simultaneously when he captured the lightweight title in 2016 to add to his featherweight crown. His trash-talking, showmanship, and genuine knockout power made him the sport’s crossover superstar. His boxing match against Floyd Mayweather in 2017 generated over 4.4 million pay-per-view buys in the United States alone and his UFC fights consistently broke the organisation’s own records.
McGregor’s business ventures — most notably his Proper No. Twelve Irish whiskey brand, sold for a reported $600 million — have made him one of the wealthiest athletes in the world. For the latest on McGregor and the UFC, the official UFC website provides comprehensive fighter profiles and event coverage.
2. Jon Jones — The Greatest Fighter of All Time
Jon Jones is widely considered the most naturally gifted fighter in MMA history. He dominated the UFC Light Heavyweight division for over a decade, capturing the title at just 23 years old in 2011 and successfully defending it a record 11 times. His combination of reach, athleticism, creativity, and unorthodox striking made him virtually impossible to fight effectively. Jones later moved up to heavyweight and won the UFC Heavyweight Championship in 2023 with a first-round submission of Ciryl Gane, cementing his status across two weight classes.
3. Georges St-Pierre — The Canadian Icon
Georges St-Pierre is the most technically accomplished fighter in MMA history. The Canadian icon won the UFC Welterweight Championship twice and also captured the Middleweight title in 2017, making him a two-division champion across an extraordinary career spanning 12 years. GSP’s wrestling, striking, and game-planning were at a level nobody in his division could match for the best part of a decade. He retired undefeated in championship bouts and is universally regarded as one of the three greatest fighters the sport has produced.
4. Khabib Nurmagomedov — The Eagle
Khabib Nurmagomedov retired from MMA with a perfect professional record of 29 wins and zero defeats, including 13 consecutive victories inside the UFC. His dominant grappling game, built on a Sambo and wrestling foundation from his upbringing in Dagestan, Russia, made him essentially impossible to defeat once he secured a takedown. His defeat of Conor McGregor at UFC 229 in 2018 to win the lightweight title is one of the most viewed events in UFC history. Khabib’s retirement in 2020 following the death of his father was an emotional moment that resonated far beyond MMA.
5. Anderson Silva — The Spider
Anderson Silva held the UFC Middleweight Championship for a record 2,457 days and compiled a UFC record winning streak of 16 consecutive victories. The Brazilian’s striking game was so far ahead of his opponents during his peak years from 2006 to 2012 that he frequently taunted his opponents mid-fight before producing finishing sequences of breathtaking beauty. His knockout of Forrest Griffin in 2009, where he dodged every punch thrown at him before landing a single shot for the finish, is among the most famous moments in UFC history.
6. Ronda Rousey — The Pioneer
Ronda Rousey did not just compete in women’s MMA — she created it at the highest level. The first female fighter signed by the UFC, Rousey won the first ever UFC Women’s Bantamweight Championship in 2012 and successfully defended it six times. Her armbar finish, developed from an Olympic judo background, ended fights in seconds and made her the most dominant champion in the UFC at the time regardless of gender. She was ranked the number one pound-for-pound fighter in the world by multiple media outlets during her peak. Rousey’s mainstream celebrity — including Hollywood roles — made her the most famous female combat sports athlete of the modern era.
7. Fedor Emelianenko — The Last Emperor
Fedor Emelianenko is considered by a significant portion of MMA purists to be the greatest heavyweight fighter in the history of the sport. His run of victories in PRIDE Fighting Championships from 2003 to 2010 included defeats of virtually every major heavyweight contender of the era and covered a stretch of over 30 consecutive wins at the highest level of competition. His combination of sambo base, heavy hands, and extraordinary composure under pressure made him a near-mythological figure in MMA circles worldwide.
8. Chuck Liddell — The Iceman
Chuck Liddell was the UFC’s first genuine mainstream star. His two-time UFC Light Heavyweight Championship reign in the mid-2000s coincided with the UFC’s first major television expansion and his aggressive knockout-seeking style made him the perfect advertisement for the sport. Liddell’s fights with Randy Couture were the UFC’s first true rivalry and his knockouts of former champions and top contenders introduced MMA to millions of fans who would not otherwise have watched the sport. He is a primary reason the UFC became the organisation it is today.

9. Daniel Cormier — The Double Champ
Daniel Cormier is one of only three fighters in UFC history to have held championships in two different weight classes simultaneously. He won the UFC Light Heavyweight Championship and the UFC Heavyweight Championship, becoming the first fighter to simultaneously hold titles in two weight categories when Jon Jones — his arch-rival — was stripped of the light heavyweight title. Cormier’s wrestling credentials, refined during his Olympic career representing the United States, combined with devastating power made him one of the most dangerous fighters in the sport’s history at any weight.
10. Stipe Miocic — The Greatest Heavyweight Champion
Stipe Miocic holds the record for the most consecutive UFC Heavyweight Championship defences in history, defending the title three times before losing it to Daniel Cormier. He recaptured the belt in the rematch and went on to defend it further, making him the most successful heavyweight champion in UFC history. A working firefighter from Cleveland, Ohio during his fighting career, Miocic’s combination of technical boxing, wrestling, and exceptional chin made him the standard-bearer for heavyweight excellence across nearly a decade at the top of the division.
