Every great sport needs great rivalries. MMA has produced some of the most intense, personal, and technically brilliant rivalries in the history of combat sports. Here are the ten that matter most.
1. Jon Jones vs. Daniel Cormier
The greatest rivalry in MMA history, and it's not close. Two generational talents who genuinely disliked each other. Jones was the prodigy who couldn't stay out of trouble. Cormier was the Olympic wrestler who did everything right and still couldn't win the one fight that mattered most.
They fought twice. Jones won both times. The second was overturned due to a failed drug test. Cormier went on to become a two-division champion. Jones moved to heavyweight and dominated. The rivalry ended without a clean resolution, which somehow makes it more compelling.
2. Conor McGregor vs. Nate Diaz
This wasn't about belts. It was about egos. McGregor was the biggest star in the sport. Diaz was the guy who didn't care. When Diaz choked out McGregor at UFC 196, it was the biggest upset in modern UFC history. When McGregor won the rematch at UFC 202 in one of the best fights ever, it proved he was more than hype.
The trilogy fight never happened. It probably should have.
3. Stipe Miocic vs. Daniel Cormier
A trilogy at heavyweight that delivered three completely different fights. Cormier knocked out Miocic in the first. Miocic adjusted and stopped Cormier in the second with body shots. The third was competitive until Miocic pulled away late. This rivalry had respect, adjustment, and heart -- everything a trilogy needs.
4. Chuck Liddell vs. Tito Ortiz
The rivalry that made the UFC mainstream. Liddell was the brawler with the mohawk. Ortiz was the heel who talked trash. Their fights on the early Spike TV cards drew numbers that proved MMA could be mainstream entertainment. Liddell won 2 of 3, and both became legends of the sport's growth era.
5. Dustin Poirier vs. Conor McGregor
Three fights, three different stories. McGregor starched Poirier in 2014. Poirier knocked out McGregor in 2021. The third fight ended with McGregor breaking his leg. The rivalry showed McGregor's decline and Poirier's evolution into one of the most complete lightweights ever.
6. Zhang Weili vs. Joanna Jedrzejczyk
UFC 248 was the fight that changed how people talked about women's MMA. Five rounds of non-stop action that left both fighters looking like they'd been through a war. Jedrzejczyk's forehead was literally deformed. It was violence as art, and it elevated both fighters forever.
7. Randy Couture vs. Chuck Liddell
Before Liddell vs. Ortiz, there was Couture vs. Liddell. The wrestler vs. the striker. Couture won the first fight. Liddell won the next two. It was the foundation for every "wrestler vs. striker" debate that's happened since.
8. Anderson Silva vs. Chael Sonnen
Sonnen talked more trash than anyone in the sport's history. He backed it up by dominating Silva for 4.5 rounds at UFC 117 before getting submitted. Silva was the untouchable champion. Sonnen was the guy who almost proved he wasn't. Their rivalry made both of them bigger stars.
9. Khabib Nurmagomedov vs. Conor McGregor
The build-up included a bus attack, religious trash talk, and the most toxic press conference in UFC history. The fight ended with Khabib choking out McGregor and jumping the fence to attack his corner. It was chaos, but the fight itself was a dominant Khabib performance that proved the grappler beats the striker at the highest level.
10. Cain Velasquez vs. Junior dos Santos
The best heavyweight trilogy of the modern era. JDS knocked out Cain in the first fight. Cain came back and dominated JDS for 10 rounds across two rematches in a way that redefined what heavyweights could do. Cain's pressure was otherworldly.
Great rivalries aren't just about wins and losses. They're about the story. The human element. Two people who bring out the absolute best in each other, even when they can't stand each other. That's what makes this sport.
