The most famous undefeated boxer retired 2007 was Floyd "Money" Mayweather Jr., who walked away from boxing in June 2007 with a perfect 41-0 record. The surprising fact? His retirement lasted less than 18 months — he returned in September 2009 and eventually finished his career 50-0, the best record in modern boxing history.
Many fans searching for the undefeated boxer retired 2007 story get the timeline wrong. They mix up his first retirement with his second, or credit the wrong records to his 2007 exit. This confusion makes it hard to separate fact from myth.
This guide breaks down who the undefeated boxer retired 2007 actually was, why he left, what his record was, how the comeback unfolded, and how you can verify every claim yourself using official boxing databases.
Who Was the Undefeated Boxer Who Retired in 2007?
Floyd Mayweather Jr. is the answer. The undefeated boxer retired 2007 fans remember best defeated Oscar De La Hoya by split decision in May 2007 to win the WBC super welterweight title in one of the highest-grossing pay-per-view fights of its era. Just weeks later, in June 2007, he announced his retirement from professional boxing.
At the time of that retirement, his professional record stood at 41 wins, 0 losses, 25 knockouts. He had held world titles in five weight classes, from super featherweight to super welterweight. Ring Magazine ranked him among the top pound-for-pound fighters in the world.
A common point of confusion: Ricky Hatton and Joe Calzaghe were also undefeated stars in 2007, but neither retired that year. Calzaghe retired undefeated in 2009 (46-0). The undefeated boxer retired 2007 trivia quizzes are looking for is Mayweather, not Calzaghe.
How to apply this: If you're fact-checking a boxing trivia question, anchor it to the date and the record — 2007 plus 41-0 points to Mayweather, not Calzaghe.
Why Did Mayweather Retire at the Peak of His Career?
Mayweather said he wanted to leave the sport while healthy, wealthy, and on top. In 2007 interviews, the undefeated boxer retired 2007 headlines focused on explained that he had nothing left to prove and wanted to focus on his promotional ventures and family.
He had just earned the biggest payday of his career against De La Hoya and held leverage no other fighter had.
The pressure behind the decision was real. Boxing at the elite level carries long-term health risks, and Mayweather watched older fighters struggle after long careers. Leaving undefeated protected both his body and his legacy.
The retirement also made business sense. As BoxRec, the sport's most widely used fight database, documents, his 2007 exit preceded his return as a self-promoted headliner — giving him a larger share of revenue than he'd earned under previous promoters.
How to apply this: When evaluating any athlete's "legacy move," look at three levers: health risk, contract leverage, and post-career business plans. Mayweather maximized all three.
What Was His Exact Record When He Retired in 2007?
Here is the breakdown the undefeated boxer retired 2007 record that fighters and fans often get wrong:
| Fact | Detail at 2007 retirement | What to verify |
|---|---|---|
| Pro record | 41-0-0 | BoxRec fight log |
| Titles held | 5 weight divisions | WBC/WBA/IBF records |
| Final 2007 win | Oscar De La Hoya (split decision) | PPV result archives |
| Knockout rate | 25 stoppage wins | CompuBox tallies |
| Retirement date | June 2007 | Press conference coverage |
| Comeback | September 2009 vs. Juan Manuel Márquez | Fight results |
The most common mistake is citing 49-0 or 50-0 as the undefeated boxer retired 2007 record. Those numbers belong to his final career tally, reached only after two comebacks. His retirement in June 2007 followed his win over De La Hoya by about five weeks.
How to apply this: Pull up his fight log on BoxRec and sort by date — you'll see the June 2007 gap in his fight history instantly.
How Did the Comeback Change His Legacy?
Mayweather returned on September 19, 2009, defeating Juan Manuel Márquez by unanimous decision. He later beat Shane Mosley, Victor Ortiz, Canelo Álvarez, Marcos Maidana (twice), Manny Pacquiao, André Berto, and finally Conor McGregor in 2017.
That final win pushed him to 50-0, surpassing Rocky Marciano's famous 49-0. The International Boxing Hall of Fame, which inducted the undefeated boxer retired 2007 icon in 2021, recognizes him as one of the most commercially successful fighters ever. The International Boxing Hall of Fame maintains official records of his induction and career honors.
One important nuance: a retirement isn't final in boxing. Fighters frequently return, which is why analysts treat the undefeated boxer retired 2007 moment as his first retirement, not the end of his career.
How to apply this: Always date a fighter's retirement claim — "retired undefeated in 2007" and "retired undefeated in 2017" describe two different Mayweather exits.

Frequently Asked Questions About undefeated boxer retired 2007
Who else retired undefeated around 2007?
Joe Calzaghe retired in February 2009 at 46-0, and Sven Ottke retired in 2007 at 34-0 — so Ottke is a legitimate secondary answer to the undefeated boxer retired 2007 question. Ottke, a German super middleweight, stepped down in March 2007 after defending his IBF title more than 20 times.
If a quiz allows European champions, Ottke fits; most quizzes mean Mayweather.
Did Mayweather retire again after 2007?
Yes, twice more. He retired briefly after beating André Berto in September 2015, then returned in August 2017 to fight Conor McGregor. That 2017 win took him to 50-0. Unlike the undefeated boxer retired 2007 exit, the 2017 retirement came after a crossover event, which is why purists distinguish between his competitive résumé and his exhibition-era earnings.
Was his 2007 retirement announced at a specific event?
It was announced via media statements in June 2007, roughly five weeks after the De La Hoya fight, rather than at an in-ring ceremony. Mayweather told reporters he was stepping away to focus on business ventures and personal matters.
Because there was no farewell bout, some fans doubted the undefeated boxer retired 2007 announcement was genuine — skepticism that proved justified.
Why didn't the Mayweather-Pacquiao fight happen in 2007?
Talks existed as early as 2009, but the fight fell through over drug-testing protocols and revenue splits, not 2007 scheduling. It finally happened in May 2015, when Mayweather won by unanimous decision. Had it occurred during his prime years, both fighters' purses and records would look different today.
How does his 50-0 compare to Rocky Marciano's 49-0?
Marciano retired in 1956 at 49-0 with 43 knockouts, a higher KO rate but fewer title defenses across multiple divisions. The undefeated boxer retired 2007 champion fought 21 more professional bouts across five weight classes against deeper opposition pools.
Historians generally rank both among the greatest records, but context — era, division depth, opposition quality — matters more than the raw number.
