The 1965 Amateur World Series was an international baseball tournament held in Cartagena, Colombia from February 12 through February 27, 1965. It was the 16th Amateur World Series. The Cuban national team was denied a chance to defend its title as Colombia, then run by a right-wing regime, refused to grant visas to Cuba's players.
