Top 10 Boxers by Career Knockouts
Career knockout counts are dominated by boxers from the 1940s-1960s, when fighters had 100+ professional fights. Modern boxers fight far fewer bouts — Floyd Mayweather had 50, Manny Pacquiao 72 — so reaching 50+ KOs is rare in the modern era.

How Boxing Knockouts Are Counted
A ‘KO’ (knockout) in professional boxing means the opponent could not continue after a 10-second count. A ‘TKO’ (technical knockout) is when the referee stops the fight because one boxer cannot intelligently defend. Most career-KO statistics combine both. Both BoxRec and World Boxing News maintain authoritative records.
Old-era fighters look dominant because they fought far more often. Sugar Ray Robinson had 200 career fights between 1940 and 1965; modern world champions retire with 30-50 fights. Archie Moore’s 131 KOs (across 220 fights) reflects both elite power and a 27-year career.
Heavyweights typically have higher KO percentages. Mike Tyson’s 44 KOs in 50 wins (88%) ranks among the highest KO ratios for an elite heavyweight. Tyson Fury, by contrast, has 24 KOs in 34 wins (71%) — still above average but lower than Tyson’s brute-force style.
Frequently Asked Questions
Who has the most boxing knockouts?
Archie Moore at 131 KOs across his career (1936-1963). Sugar Ray Robinson is second at 109. Both are well ahead of any modern fighter.
How many KOs did Mike Tyson have?
Mike Tyson finished his career with 44 KOs in 50 wins (88% KO rate) — among the highest knockout percentages of any elite heavyweight champion.
Why do older boxers have more KOs?
Pre-1970s fighters had far more career bouts. Sugar Ray Robinson fought 200 times; Floyd Mayweather Jr. 50. More fights = more chances for KOs, regardless of power.
What's the difference between KO and TKO?
KO: opponent cannot continue after the count. TKO: referee stops fight because one boxer cannot defend. Career stats typically combine both as ‘knockouts.’
Note: Career KO counts per BoxRec at end-of-career or as of late 2024. Active boxers continue to add KOs.
