The 2013 Pan American Junior Championships was held at the Estadio Alfonso Galvis Duque in Medellín, Colombia, from 23 to 25 August. The competition was originally scheduled for 2–4 August in Lima, Peru. Lima was ruled out as the host and the dates were also amended in April, due to the clash with the 2013 World Games in Cali and its proximity to the 2013 World Championships in Athletics.
