Who Has Dustin Poirier Fought? (Key Opponents & Results)
Poirier’s resume reads like a who’s who of the UFC lightweight and featherweight divisions. He has shared the Octagon with five former UFC champions and holds wins over multiple Hall of Fame-caliber fighters.
The Conor McGregor Trilogy
The rivalry with Conor McGregor defined a significant chapter of Poirier’s career. The two first met at UFC 178 in 2014, where McGregor won by first-round TKO. They met again at UFC 257 in January 2021, and Poirier avenged the loss with a second-round TKO. The trilogy concluded at UFC 264 on July 10, 2021, where Poirier won by TKO due to a doctor stoppage after McGregor suffered a broken leg in the first round. That victory made Poirier the first fighter to defeat McGregor by knockout in an MMA bout, according to Wikipedia.
Poirier’s southpaw stance and high-volume boxing pressure were key factors in his success against McGregor. He closed distance effectively, targeted the legs and body, and overwhelmed the Irishman with combinations in both rematch wins.
Max Holloway Rivalry
Poirier and Max Holloway fought twice at featherweight in 2012 and 2016, with Holloway winning both by submission and decision respectively. They met for a third time at UFC 236 in April 2019 for the interim lightweight title, and Poirier won by unanimous decision to claim the belt. Their fourth and final meeting occurred at UFC 318 on July 19, 2025, where Holloway won by unanimous decision in what became Poirier’s retirement fight, as documented by ESPN.
Other Notable Opponents
Beyond the McGregor and Hollowax rivalries, Poirier scored statement wins over Justin Gaethje (TKO, 2018), Eddie Alvarez (TKO, 2018), and Anthony Pettis (submission, 2017). He also fought for undisputed titles against Khabib Nurmagomedov (submission loss, 2019), Charles Oliveira (submission loss, 2021), and Islam Makhachev (submission loss, 2024). According to official stats from UFC Stats, Poirier has 13 first-round finishes across his career.
