Dustin Poirier

Profile Overview

Dustin Poirier (born January 19, 1989) is an American former professional mixed martial artist who competed from 2009 to 2025. He formerly competed in the Featherweight and Lightweight divisions of the Ultimate Fighting Championship (UFC), where he was an interim UFC Lightweight Champion. Poirier also challenged three times for the undisputed UFC Lightweight Championship and twice for the BMF title. Although he never captured an undisputed UFC title, Poirier is frequently cited by MMA media and fellow fighters as one of the greatest lightweights in the sport's history, as well as one of the greatest fighters never to have won an undisputed belt.
Poirier is tied with Edson Barboza for the second most Fight of the Night awards in UFC history, with 10. He has landed 1,861 career significant strikes, the fifth most in UFC history, including 1,308 in the lightweight division, which ranks second in divisional history. His 11 career knockout victories are tied for the third most in modern UFC history, with nine of those coming at lightweight, also the second most in the division. Fight Matrix currently ranks him as the fifth-greatest lightweight fighter of all time and the 26th-greatest fighter pound for pound.
Poirier's rematch and trilogy bouts against Conor McGregor rank among the highest-selling pay-per-view events in UFC history. UFC 257 generated approximately 1.6 million buys, while UFC 264 drew around 1.8 million. He reportedly earned $1 million for UFC 257 and $10 million for UFC 264, the latter marking the largest payday of his career.
