The men's flyweight competition of the boxing events at the 2015 Pan American Games in Toronto, Ontario, Canada, was held between the 19 and 25 of July at the Oshawa Sports Centre.

Flyweights is limited to those boxers weighing less than or equal to 52 kilograms.

[1][2][3] 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.
