#6 – Georges St-Pierre vs. B.J. Penn

Georges St-Pierre and B.J. Penn are two of the most respected and accomplished fighters in MMA history. When they first faced off at UFC 58 in 2006, it was an opportunity for Penn, the former UFC Welterweight Champion, to re-establish himself as a dominant force after a brief stint outside the promotion. For St-Pierre, it was a chance to solidify his status as the next great welterweight.

In their first encounter, St-Pierre edged out Penn in a razor-thin split decision victory. The fight was so closely contested that it left fans clamoring for a rematch. That rematch would come at UFC 94 in 2009, with both fighters now holding UFC titles – St-Pierre as the reigning Welterweight Champion and Penn as the Lightweight Champion.

Their second bout was a much more decisive affair, with St-Pierre utilizing his superior wrestling and relentless ground and pound to force Penn’s corner to throw in the towel after four grueling rounds. Despite the definitive outcome, the fight was not without controversy, as accusations of greasing against St-Pierre’s corner added an extra layer to what is regarded as one of the biggest UFC rivalries in history.

#5 – Dominick Cruz vs. Urijah Faber

Dominick Cruz and Urijah Faber’s rivalry is one of the longest-lasting and most significant in the history of MMA. Their first encounter dates back to 2007, with both fighters possessing contrasting styles and attitudes. Faber, the charismatic California Kid, was the reigning WEC Featherweight Champion at the time, while Cruz, the scrappy underdog, was looking to make a name for himself.

Their first bout took place at WEC 26, where Faber submitted Cruz in the first round with a guillotine choke. It would be the only loss Cruz would suffer in his career until 2016. The two would continue to talk trash and build up their rivalry, leading to a highly anticipated rematch in 2011 at UFC 132. This time, Cruz got the better of Faber, winning a close unanimous decision and retaining his UFC Bantamweight Championship.

The rivalry didn’t end there, though. Cruz and Faber would continue to trade verbal jabs and coach against each other on The Ultimate Fighter 15, setting up their trilogy fight at UFC 199 in 2016.

Throughout their battles, both Cruz and Faber showcased their incredible skillsets and heart, creating what is undoubtedly one of the best UFC rivalries of all time.

#4 – Tito Ortiz vs. Chuck Liddell

Tito Ortiz and Chuck Liddell’s rivalry is a prime example of how personal animosity can lead to legendary battles inside the Octagon. The two fighters were once friends and training partners, but their friendship disintegrated when they found themselves on a collision course for the UFC light heavyweight title.

Their first encounter took place at UFC 47 in 2004, with Liddell emerging victorious via second-round knockout. The fight was a pivotal moment in the evolution of the UFC, as it helped elevate the promotion to new levels of popularity.

A highly anticipated rematch between Ortiz and Liddell occurred at UFC 66 in 2006. Once again, Liddell proved to be the superior fighter, defeating Ortiz by third-round TKO to retain his light heavyweight title. The bad blood between the two fighters continued even after their in-cage battles, as both men remained prominent figures in the sport.

Their rivalry culminated in a trilogy fight in 2018 under the Golden Boy Promotions banner, with Liddell coming out of retirement to face Ortiz one last time. Ortiz would finally secure a victory over his longtime rival, ending one of the biggest UFC rivalries on a high note.

#3 – Anderson Silva vs. Chael Sonnen

Anderson Silva and Chael Sonnen’s rivalry is a tale of two vastly different personalities and fighting styles. Silva, the dominant and enigmatic champion, was the epitome of grace and skill inside the Octagon. Sonnen, on the other hand, was an unapologetic trash-talker with a relentless wrestling style. Their contrasting personas and styles made for an enthralling rivalry.

Their first encounter at UFC 117 in 2010 was a classic. Sonnen dominated Silva for nearly five full rounds, only for Silva to secure a last-minute triangle choke submission, completing one of the most incredible comebacks in MMA history. The fight, along with Sonnen’s relentless trash-talking, captured the imagination of fans and set the stage for a highly anticipated rematch.

At UFC 148 in 2012, Silva and Sonnen met again, this time with Silva finishing the fight in the second round via TKO. The rivalry may have ended with Silva as the clear victor, but the unforgettable moments and the drama between the two fighters have solidified their place among the best UFC rivalries ever.

#2 – Conor McGregor vs. Nate Diaz

The rivalry between Conor McGregor and Nate Diaz is nothing short of electric, showcasing the magnetic personalities and exceptional skills of both fighters. Their story began in 2016 when Diaz stepped in on short notice to face McGregor at UFC 196. In a shocking turn of events, Diaz submitted the seemingly unstoppable McGregor, handing him his first loss in the UFC.

The defeat only fueled McGregor’s desire for redemption, setting the stage for one of the most highly anticipated rematches in MMA history. At UFC 202, the two warriors engaged in a thrilling five-round battle, with McGregor emerging victorious by majority decision. The back-and-forth nature of the fight and the razor-thin margin between victory and defeat only intensified the rivalry.

While both fighters have gone on to face other opponents, the possibility of a trilogy fight between McGregor and Diaz continues to intrigue fans. Their explosive personalities, trash-talking antics, and incredible heart displayed inside the cage make this rivalry one of the biggest UFC rivalries of all time.

#1 – Jon Jones vs. Daniel Cormier

The rivalry between Jon Jones and Daniel Cormier is one for the ages, fueled by genuine animosity, competitive fire, and two of the greatest fighters in UFC history. Their story begins in 2010 when they met backstage at a UFC event. What started as a friendly encounter quickly turned sour, with Jones taking a jab at Cormier’s wrestling credentials. This sparked a bitterness between the two that would last for years.

The rivalry heated up in 2014 when they were scheduled to fight at UFC 178. At a press conference promoting the event, the two men got into a brawl, further escalating tensions. Due to an injury, Jones had to pull out of the fight, but the stage was set for an epic showdown. They finally met at UFC 182 in 2015, with Jones successfully defending his light heavyweight title. However, their story was far from over.

In 2016, Jones was stripped of his title and suspended, leading to Cormier being crowned the new champion. When they met again at UFC 214, Jones reclaimed the belt with a knockout victory, but the result was later overturned due to a failed drug test. Despite never having a third fight, the rivalry between Jon Jones and Daniel Cormier remains one of the most intense and significant in MMA history. Their heated exchanges, incredible performances, and undeniable talent mean that this ranks as our best and biggest UFC rivalry of all time.
