The 63 fighters with the most knockouts in the UFC
Every fighter on this list is ranked on one number: wins by KO or TKO. Nothing else is weighed, and the figures each ranking rests on are in the table. These are UFC bouts only.

How this list is made
Ranked on knockouts: wins by KO or TKO. Fighters are ranked on that number alone and on nothing else. Where two are level they share a rank, and the list runs past fifty when fiftieth place is shared, because splitting a tie would mean choosing between them on no stated basis.
These are UFC bouts and nothing else. A fighter’s record in other promotions is not counted, so someone with a long career elsewhere can appear here with a short one. This is not a career record and does not claim to be.
312 bout records carry no usable result and are counted in nothing — not as a win, a loss or a bout. A bout record is one fighter’s side of one fight, so a fight between two fighters who each have a page here appears as two of them.
