Oscar De La Hoya is an American former professional boxer.

As a boxer, he competed from 1992 to 2008, winning 11 world titles in six weight classes, including the lineal championship in three weight classes. He is ranked as the 15th best boxer of all time, pound for pound, by BoxRec. Nine of his victorious fights received a 5-Star rating from BoxRec. De La Hoya was nicknamed "The Golden Boy of boxing" by the media when he represented the United States at the 1992 Summer Olympics where, shortly after having graduated from James A. Garfield High School, he won a gold medal in the lightweight division, and reportedly "set a sport back on its feet." De La Hoya was named The Ring magazine Fighter of the Year in 1995, and was its top-rated fighter in the world, pound for pound, in 1997 and 1998. De La Hoya generated approximately $700 million in pay-per-view income, making him the top pay-per-view earner before being surpassed by Floyd Mayweather Jr. and Manny Pacquiao. He announced his retirement as a fighter in 2009, following a professional career spanning 16 years.

In 2002, De La Hoya founded Golden Boy Promotions, a combat sport promotional firm. He is the first American of Mexican descent to own a national boxing promotional firm, and one of the few boxers to take on promotional responsibilities while still active. In 2018, he began promoting MMA matches as well, beginning with a 2018 trilogy bout between long-time rivals Chuck Liddell and Tito Ortiz, with the inaugural Golden Boy MMA event scheduled for November 24, 2018.
