📉 About Most KO/TKO Losses in UFC History
This leaderboard ranks UFC fighters by total career losses inside the promotion, with tabs to break those defeats down by how they happened — knockout, submission, decision, or any finish. A loss is counted whenever the opposing fighter is recorded as the winner of a bout, and we tally them straight from each fighter's full fight history.
Why the loss leaders are usually respected veterans
It's tempting to read a long loss column as a knock on a fighter, but the names at the top of this list are almost always grizzled, long-serving competitors who stuck around the UFC for years and shared the cage with elite opposition. You don't accumulate 15 or 20 UFC losses without also having the toughness to keep getting rebooked, the durability to keep competing, and enough wins to justify a long roster spot. Many of the sport's most beloved action fighters and gatekeepers live near the top here.
The method tabs tell a deeper story than the raw total. A fighter with lots of decision losses was rarely hurt but often out-pointed; one with many KO or submission losses may have a specific hole in their game. Cross-reference this with our never been finished iron-chins list and the most wins leaderboard to see the full arc of a long career, and open any fighter profile to see exactly who handed out those defeats.
