Boxing at the 2023 Pan American Games – Men's 80 kg

There was a quota of 130 boxers to compete at the games (ten per event). The host nation (Chile) received automatic qualification spots for all events. The remainder of the spots were awarded through various qualifying tournaments.^[5] However, the International Olympic Committee later decided the competition was an open registration event, meaning any NOC could enter a boxer into the event.^[6]

Like all Pan American boxing events, the competition is a straight single-elimination tournament. Both semifinal losers are awarded bronze medals, so no boxers compete again after their first loss. Bouts consist of 3 rounds "10-point must" scoring system used, where the winner of each round must be awarded 10 points and the loser a lesser amount, and the elimination of the padded headgear. Five judges scored each bout. The winner will be the boxer who scored the most at the end of the match.^[5]
