Boxing at the 2015 Pan American Games – Men's heavyweight

The men's heavyweight competition of the boxing events at the 2015 Pan American Games in Toronto, Ontario, Canada, was held between the 18 and 24 of July at the Oshawa Sports Centre. The defending champion is Lenier Pero of Cuba. Heavyweights is limited to those boxers weighing less than or equal to 91 kilograms.

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 a 3 rounds "10-point must" scoring system used in the pro game, 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.
