The heavyweight division in mixed martial arts (MMA) generally groups fighters between 206–265 lb (93.4–120.2 kg).
Although many ambiguities exist within the lowerweight classes regarding division naming and weight limits, the Heavyweight division is, for the most part, uniform. The Ultimate Fighting Championship (UFC) and most other North American MMA organizations such as Bellator MMA, WSOF, and King of the Cage (KOTC) abide by this interpretation to their 206–265 lb athletes as heavyweights. ONE Championship's heavyweight division is at 226–265 lb. Pancrase's overweight division was 198.4–220.5 lb (90.0–100.0 kg) before being revised to its current 205–264.5 lb (93.0–120.0 kg).
The heavyweight upper weight limit, as defined by the Nevada State Athletic Commission and the Association of Boxing Commissions is 265 lb (120 kg).
