Andre Michael Berto (born September 7, 1983) is a professional boxer who holds dual Haitian and American citizenship.

In the late 2000s he was considered a rising star in the welterweight division, as well as a highly regarded young prospect in boxing.

He reached the peak of his career in 2011, holding the WBC welterweight title which he had won in 2008 and made five defenses, and was ranked as the world's third best welterweight, behind then-top stars Manny Pacquiao and Floyd Mayweather Jr. Berto's success was cut short after his first career loss to Victor Ortiz in 2011, which won Fight of the Year honors by The Ring magazine.

On December 12, 2006, at the Alltel Arena in North Little Rock, Arkansas, Berto stepped up in competition and fought Miguel Figueroa.

[7] On September 29, 2007, at Boardwalk Hall in Atlantic City, New Jersey, Berto defeated David Estrada by eleventh-round technical knockout to win the NABF welterweight title.

Estrada made it to his feet, but could not defend himself as Berto attacked with more damaging shots that prompted the referee to jump in and stop the fight.

[8] On February 9, 2008, at the Pechanga Resort & Casino in Temecula, California, Berto fought Michael Trabant in his first defense of the NABF welterweight title.

[13] Berto made the second defense of his title on January 17, 2009, at the Beau Rivage in Biloxi, Mississippi, against former WBA welterweight champion Luis Collazo.

However, Berto announced that he was withdrawing from his title unification bout against Mosley on January 18, 2010, due to family loss in the Haiti earthquake.

Berto successfully defended his WBC welterweight title, stopping an overmatched Freddy Hernandez at 2:07 of the first round putting himself in line for a shot at Floyd Mayweather Jr.[21] He hammered Hernandez with a left hook, then floored him with a straight right during the co-feature fight of the Juan Manuel Márquez-Michael Katsidis lightweight championship bout.

[citation needed] On April 16, 2011, Berto's reign as WBC welterweight champion came to an abrupt end in a fight which proved to be one of the biggest upsets of 2011 at the hands of a moving up in weight form 140 "Vicious" Victor Ortíz.

Ortiz defeated Berto by unanimous decision in a fight that was named The Ring magazine's "Fight of the Year" for 2011 with 4 ruled knockdowns going into the fight Berto was undefeated but was facing complaints of being unproven at the highest level and a lack of notable, quality opposition on his record of 27–0–21 Knockouts and the loss stopped him from landing a bout with Floyd Mayweather Jr.[22] On September 3, 2011, Berto returned after his defeat to Victor Ortíz to face IBF welterweight champion and Ring Top 10 welterweight Dejan Zavec.

[23] Berto relinquished his IBF welterweight title rather than face mandatory challenger Randall Bailey in order to facilitate the rematch with Ortiz because he wanted the opportunity to avenge his only defeat (at the time).

[26] Josesito Lopez replaced Berto and fought Ortiz on the scheduled date at the Staples Center in Los Angeles.

[28] Following an 8-month lay-off after losing to Guerrero, Berto eventually returned to the ring to face Jesús Soto Karass on July 27, 2013, at the AT&T Center in San Antonio.

[29] On August 19, 2014, after a 14-month lay-off following consecutive defeats where he used most of that time nursing his injured shoulder, it was announced that Berto would fight journeyman Steve Upsher Chambers (24-3-1, 6 KO) on September 6 on Showtime in a 10-round bout, a day before his 31st birthday.

[32] On January 22, 2015, it was announced that Berto would fight Josesito López (33–6, 19 KOs) on March 13, as part of the new Premier Boxing Champions series on Spike TV.

He beat the count, another right hand put Lopez down again causing the referee to stop the fight at 1 minute and 3 seconds.

[35] On August 4, 2015, it was announced that, after months of speculation, a bout between Berto and Floyd Mayweather Jr. in Las Vegas would indeed take place on September 12, 2015.

Berto pushed the pace, but his aggressiveness fell short as Mayweather was highly mobile and closed the distance consistently.

[37] Mayweather hurt his left hand at the end of the ninth round but remained comfortable throughout the rest of the fight, winning via unanimous decision 117–111, 118–110, and 120–108.

[41] Five years after their first slugfest, Berto and Victor Ortíz finally met in a rematch on April 30, 2016, at the StubHub Center in Carson, California.

Ortiz went down twice in the 4th round and although he was able to beat both counts, he didn't answer to referee Jack Reiss when asked if he wanted to continue.

[42] On February 13, 2017, it was announced that a deal was close to being made between Berto and former welterweight world champion Shawn Porter (26-2-1, 16 KOs).

[44][45][46] Halfway through the press conference, promoter Lou DiBella confessed that he received a phone call from WBC president Mauricio Sulaiman and he reported the fight would be a final eliminator.

[52] ESPN's Dan Rafael announced on April 28, 2018, that a deal had been reached for Berto to fight former 2-weight world champion Devon Alexander (27-4-1, 14 KOs) on the Errol Spence Jr. vs. Carlos Ocampo undercard on June 16 at The Ford Center at The Star in Frisco, Texas, however the fight did not take place.

[53] On June 25, the fight was slated to take place on the Mikey Garcia vs. Robert Easter Jr. lightweight unification card at the Staples Center on July 28 on Showtime.

[54] The fight would instead main event its own card on August 4 at the Nassau Veterans Memorial Coliseum in Uniondale, New York, on Fox.

Websites, Boxing Scene and BadLeftHook had Alexander the winner and felt although Berto caught up in the later rounds, he did not do enough to win the fight.

[61] In a March 2010 column he wrote for The New York Times, Berto described some of his efforts for Project Medishare in Haiti after the earthquake, as well as relating that he is frequently mistaken for American football star Reggie Bush.
