Who is the best boxer by record?

When evaluating the careers of the greatest boxers, their win-loss records provide a key data point. Examining boxers’ total number of wins, losses and draws helps quantify their success and rank them historically. The boxers with the highest win percentages and longest undefeated streaks make strong cases as the best in the sport’s history.

How many wins did the top boxers have?

The boxer with the most wins ever is little-known 19th century English fighter Len Wickwar, who compiled an eye-popping 339-0-9 record. However, Wickwar primarily fought in unregulated “fairground boxing” booths against overmatched opponents. His record is not sanctioned or recognized by authoritative boxing record-keepers.

Among prominent championship boxers, the fighter with the most officially recognized wins is former welterweight champion Julio Cesar Chavez of Mexico. Chavez, considered by many experts to be the best Mexican boxer ever, compiled an official record of 107-6-2 during his dominant run from 1980 to 2005. His 88.3% win rate puts him among the sport’s all-time leaders.

Who had the highest win percentage in boxing history?

In terms of win percentage, which factors out volume of fights from a record’s impressiveness, the boxer recognized as having the best win rate ever is heavyweight champion Rocky Marciano. Marciano retired undefeated with a mark of 49-0-0, giving him a perfect 100% win rate. He held the heavyweight title from 1952-1956 and made six successful defenses.

Other boxers with historically high win percentages include Andre Ward (32-0-0, 100%), Joe Calzaghe (46-0-0, 100%) and Edwin Valero (27-0-0, 100%). However, they fought in lower weight classes than heavyweight and compiled shorter undefeated streaks than Marciano at heavyweight.

Who has the longest undefeated streak in boxing history?

The boxer with the longest undefeated streak and unbeaten run in sanctioned matches is former heavyweight champion Joe Louis. Nicknamed “The Brown Bomber,” Louis won his first 27 professional bouts after turning pro in 1934. He then earned the heavyweight crown in 1937 and held onto it until retiring undefeated in 1949, making 25 consecutive title defenses. His overall undefeated streak spanned an incredible 131 fights.

Other fighters with lengthy undefeated records include Mexican legend Julio Cesar Chavez (89-0 before his first loss), Packey McFarland (70-0 until his only career loss) and Jimmy Barry (59-0-10). But no one has matched Louis’ run of dominance at heavyweight, the sport’s glamour division.

How do iconic champions Muhammad Ali and Floyd Mayweather stack up?

Muhammad Ali and Floyd Mayweather Jr. stand out as perhaps the two most skilled and famous boxers of the modern era. How do their records size up?

Ali compiled a career mark of 56-5 with 37 knockouts. He went undefeated during the first 29 fights of his career and held the heavyweight title three different times. However, his resume took a hit from losing five fights during his career, including two losses to Joe Frazier and one to Ken Norton.

Mayweather retired undefeated at 50-0 with 27 KOs. He won world titles in five different weight classes and defeated numerous future Hall of Famers. His consistency and ability to avoid ever taking a loss give him a strong case as the best boxer of his generation and one of the best ever, regardless of weight class.

Who were the best undefeated boxers who retired early or had shortened careers?

Some all-time great boxers saw their careers end abruptly before losses could pile up on their records. Examining their dominance during their relatively short careers shows how impressive they were:

  • Rocky Marciano 49-0 – Retired as undefeated heavyweight champ.
  • Joe Calzaghe 46-0 – Undefeated super middleweight champion.
  • Edwin Valero 27-0 – Hard-hitting undefeated lightweight.
  • Tim Bradley 33-0 – Won four world titles before first career loss.
  • Ricardo Lopez 51-0-1 – Retired undefeated minimumweight legend.

These fighters likely would have continued racking up wins if not for retiring in their primes. Their perfect or near-perfect records during their short but brilliant runs stand out as models of dominance.

Which women’s boxers have been undefeated?

During the 20th century, female boxing was banned in the United States and many other countries. But once womens’ participation in the sport gained more acceptance and popularity, a number of standout talents emerged, several with perfect or near-perfect records:

  • Cecilia Braekhus 36-0 – Longest reigning welterweight champ ever, man or woman.
  • Lucia Rijker 17-0 – Pioneering Dutch boxer, inspiration for “Million Dollar Baby.”
  • Christy Martin 49-7-3 – Female trailblazer who achieved celebrity status.
  • Laila Ali 24-0 – Undefeated daughter of Muhammad Ali.
  • Anne Wolfe 24-1 – Power puncher widely regarded as best female boxer ever.

While their careers were shorter than many male boxers, these dominant female fighters proved that women can excel in the skill, science and showmanship of boxing at the highest levels.

How do the best amateur boxers compare?

Olympic and amateur boxing success does not always translate to professional glory. But many of the most accomplished amateurs ever also went on to undefeated pro careers, including:

  • Vasyl Lomachenko: 396-1 as amateur, 15-0 as pro.
  • Guillermo Rigondeaux: 463-12 as amateur, 20-1 as pro.
  • Andre Ward: 115-5 as amateur, 32-0 as pro.
  • Pernell Whitaker: 201-14 as amateur, 40-4-1 as pro.
  • Oscar De La Hoya: 223-5 as amateur, 39-6 as pro.

These boxing greats show how an extensive successful amateur background can translate to professional victories. But the more grueling professional fight schedule often hands ex-amateurs their first career losses.

Which all-time boxing greats have losses on their records?

Some of the biggest names in boxing history – including several considered by experts and fans to be among the best ever – have a number of recorded losses and failed to retire undefeated:

  • Muhammad Ali: 56-5
  • Sugar Ray Robinson: 173-19-6
  • Roberto Duran: 103-16
  • George Foreman: 76-5
  • Lennox Lewis: 41-2-1
  • Evander Holyfield: 44-10-2
  • Oscar De La Hoya: 39-6
  • Manny Pacquiao: 62-8-2

But these all-time great fighters amassed numerous championships, classic bouts and legendary resumes against top competition, cementing their places among the sport’s immortals despite having losses late in their storied careers.

Who were the best multi-division champions?

Many coveted being undisputed champions in a single weight class. But some talented boxers succeeded in winning world titles across multiple weight divisions during their careers:

Boxer Weight Classes Record
Manny Pacquiao 8 62-8-2
Oscar De La Hoya 6 39-6
Floyd Mayweather Jr. 5 50-0
Thomas Hearns 5 61-5-1
Sugar Ray Leonard 5 36-3-1

This ability to adapt, dominate and win titles across varying weight classes demonstrated these champions’ versatility and excellence across different eras and opponents.

How did famous boxers from the early 20th century fare?

In the 1900s-1920s heyday of boxing, the sport’s biggest stars regularly competed dozens and sometimes hundreds of times, both in sanctioned bouts and unsanctioned exhibitions. Their records reflected healthy totals of wins, losses and draws:

  • Jack Johnson: 73-13-10 – First Black heavyweight champ.
  • Sam Langford: 178-32-40 – Dangerous early Black standout.
  • Harry Greb: 107-8-3 – Legendary middleweight and light heavyweight.
  • Jack Dempsey: 65-6-11 – Popular heavyweight, “Manassa Mauler.”
  • Mickey Walker: 93-19-4 – First to hold titles at welter, middle and light heavy.

As boxing became more formally regulated in the late 1920s, top fighters tended to compete less frequently and lose fewer bouts.

Which fighters had the longest careers?

Some competitors managed to sustain successful careers well into their 40s, with a mix of wins, losses and draws piling up over decades in the ring:

  • George Foreman: 81-5 record, 26-year career from 1969-1997.
  • Archie Moore: 185-23-11 record, 28-year career from 1935-1963.
  • Bernard Hopkins: 55-8-2 record, 28-year career from 1988-2016.
  • Larry Holmes: 69-6 record, 28-year career from 1973-2002.
  • Sugar Ray Robinson: 173-19-6 record, 25-year career from 1940-1965.

These fighters’ ability to compete and win at the world-class level into their 40s was a testament to their skill, tenacity and longevity.

Which active boxers have the best win-loss records?

Among today’s top names and reigning champions, several stand out for sustaining minimal losses during their careers so far:

  • Canelo Alvarez: 57-2-2
  • Oleksandr Usyk: 19-0
  • Naoya Inoue: 23-0
  • Errol Spence Jr.: 28-0
  • Tyson Fury: 32-0-1

These current champions aim to continue winning at the sport’s highest levels to maintain their lofty win percentages and pursue all-time great status.


While any boxer’s overall record must be examined closely to determine the quality of opponents faced and circumstances of each bout, win-loss percentages provide a useful lens for evaluating fighters throughout history. Rocky Marciano stands out with a perfect 49-0 mark that will almost certainly never be duplicated. But plenty of all-time greats, including Muhammad Ali, Sugar Ray Robinson and Joe Louis built Hall of Fame resumes despite having losses mixed in among their many wins and iconic moments.

For active boxers today like Canelo Alvarez and others with impressive win totals and minimal losses so far, their ultimate legacies remain a work in progress. Winning or losing future big fights will significantly impact how their still-unfolding careers are remembered. But their current high win percentages have them well on their way to potential all-time great status.
