Andre Michael Berto (born September 7, 1983) is a professional boxer who holds dual American and Haitian citizenship. He is a two-time former welterweight world champion, having held the WBC and IBF titles between 2008 and 2011, as well as the WBA interim title in 2015. As an amateur he won the National Golden Gloves tournament in 2001 (at light middleweight) and 2003 (welterweight), and would represent the U.S. at the 2003 World Championships, winning a welterweight bronze medal. He also represented Haiti at the 2004 Olympics, reaching the opening round of the welterweight bracket.
Since his professional debut in 2004, Berto has become known for his toughness, formidable punching power, and fast hand speed. In the late 2000s he was considered a rising star in the welterweight division, as well as a highly regarded young prospect in boxing.
On September 12, 2015, Berto went toe-to-toe with world boxing champion, Floyd Mayweather Jr., at the MGM's Grand Garden Arena in Las Vegas on Showtime Pay-Per-View. The fight went a full twelve rounds, after which Mayweather announced his retirement from professional boxing.
