Ricardo Delgado Nogales (born July 13, 1947) is a former boxer from Mexico. He was a gold medalist at the 1968 Summer Olympics in Mexico City during his career as an amateur in the flyweight division (−51 kg). Delgado turned pro in 1969 and had limited success. After being undefeated in his first ten fights, he lost a decision to Davey Vasquez in 1971, a bout in which Delgado was knocked down once in the 5th and 6th rounds. Delgado's career went downhill after the loss and he retired four years later with a career record of having won 14, lost 12, and drawn 5.
