Antonio Pettigrew (born November 3, 1967 in Macon, Georgia) is a former American sprint athlete who specialised in the 400 meters. He came to prominence at the 1991 World Championships, where he won the 400 m gold medal and a silver medal in the 4 x 400 meters relay. He admitted to using performance-enhancing drugs between 1997 and 2001, and was stripped of his 1999 World Championship and 2000 Olympic relay gold medals.
In 2008, prosecution documents related to the trial of coach Trevor Graham listed Pettigrew as one of Graham's athletes to have used performance enhancing drugs. Pettigrew has since admitted to using performance-enhancing drugs and testified against Graham at his trial in May 2008. Although IAAF rules currently do not retrospectively alter results more than eight years after the event, Pettigrew has returned the medals he won in that period. The 2000 Sydney Olympics 4 x 400 m relay US team was stripped of their medals after Pettigrew admitted that he had used performance-enhancing drugs. He received a two-year athletics ban in 2008, although he had already retired from the track.
