Carl Williams (November 11, 1959 – April 7, 2013), nicknamed "The Truth", was an American boxer who competed as a professional from 1982 to 1997. He challenged twice for heavyweight world titles; the IBF title against Larry Holmes in 1985; and the undisputed title against Mike Tyson in 1989. At regional level he held the USBA heavyweight title from 1987 to 1991.
Williams spent his childhood in South Jamaica, Queens. He was raised by his grandmother. After his grandmother died, Williams began to box at the age of nineteen, training with the Daniel M. O'Connell Park Gym in Saint Albans, New York (also known as the New York City Recreations O'Connell Center,) walking six miles to his gym and back each day, and showing a natural talent and determination. "He's a natural, no question about that," said his trainer, Vic Hanson.
