The featherweight division in mixed martial arts refers to different weight classes:
- The UFC's featherweight division, which groups competitors within 136–145 lb (65.8 kg)
- The Shooto's featherweight division, which limits competitors to 135 lb (61.2 kg)
- The ONE Championship's featherweight division, with upper limit at 70.3 kg (155.0 lb)
- The Road FC's featherweight division, with upper limit at 144.4 lb (65.5 kg)
Ambiguity and clarification
For the sake of uniformity, most American mixed martial arts media outlets consider Featherweight competitors to be between 136 and 145 lb (60 and 66 kg). King of the Cage (KOTC) refers to its 145 lb (66 kg) division as bantamweight whereas Shooto refers to its 143 lb (65 kg) division as lightweight. The UFC uses the Nevada definition of "featherweight".
The featherweight limit, as defined by the Nevada State Athletic Commission and the Association of Boxing Commissions is 145 lb (66 kg).
