The men's freestyle 55 kg competition of the wrestling events at the 2011 Pan American Games in Guadalajara, Mexico, was held on October 23 at the CODE II Gymanasium. The defending champion was Henry Cejudo from the United States. Each bout consisted of up to three rounds, lasting two minutes apiece. The wrestler who scored more points in each round was the winner of that rounds; the bout finished when one wrestler had won two rounds (and thus the match).
