The Ultimate Fighting Championship (UFC) is a mixed martial arts (MMA) promotion, founded in 1993 by Art Davie and Rorion Gracie. The organization was purchased from its parent company SEG in 2001 by Zuffa LLC, a promotional company owned by Las Vegas casino magnates, Lorenzo Fertitta and Frank Fertitta and managed by Dana White (current president of operations).In 2016, it was sold to William Morris Endeavor (WME-IMG) for $4 billion. Since its inception, and through its Zuffa management, the UFC has remained one of the more dominant MMA promotions in the world, playing host to a wide field of MMA fighters.
This list provides an up-to-date roster of all fighters currently competing under the UFC promotional banner.

Fighters with the same number of fights are listed in order of their number of wins. Fighters with the same UFC record are listed alphabetically.
