Manuel Ramos (November 20, 1942 – June 6, 1999), nicknamed Pulgarcito (Tom Thumb), was a Mexican boxer and actor. He was the heavyweight champion of Mexico, a top world title contender in the late 1960s, and one of Mexico's most internationally successful heavyweights. On June 24, 1968, Ramos became the first Mexican to challenge for the heavyweight crown when he fought reigning champion Joe Frazier at Madison Square Garden in New York City.
