Boxing at the 1968 Summer Olympics – Flyweight

The Flyweight class in the boxing competition was the second-lowest weight class. Flyweights were limited to those boxers weighing a maximum of 51 kilograms (112.4 lbs). 26 boxers qualified for this category. Like all Olympic boxing events, the competition was a straight single-elimination tournament. Both semifinal losers were awarded bronze medals, so no boxers competed again after their first loss. Bouts consisted of six rounds each. Five judges scored each bout.

Draw
1 Cintrón was ejected from the competition after officials discovered he was underage on the morning of the first round.
