The men's Greco-Roman flyweight competition at the 1964 Summer Olympics in Tokyo took place from 16 to 19 October at the Komazawa Gymnasium.

[1] Flyweight was the lightest category, including wrestlers weighing 52 kilograms (114.6 lb).

If 2 wrestlers remained, point totals were ignored and they faced each other for gold and silver (if they had already wrestled each other, that result was used).

Bozkurt had his first loss, but with a tie and win by decision earlier, had enough points to eliminate him as well.

Hanahara and Pîrvulescu took the lead with 2 points after Wilson's loss put him at 3 (along with three other wrestlers).
