Heavyweight, Greco-Roman (>97 kilograms), Men

Date	16 – 19 October 1964
Status	Olympic
Location	Komazawa Gymnasium, Komazawa Olympic Park, Tokyo
Participants	11 from 11 countries
Format	Scoring by negative points, with negative points given for any result short of a fall. Accumulation of 6 negative points eliminated the wrestler.

The last two World Champions were Hungarian István Kozma (1962) and Soviet Anatoly Roshchin (1963). They were both in Tokyo to contest this class and ending up getting to the final round where they faced each other. Kozma had only 1 bad point after five rounds while Roshchin had 3 bad points, so when they drew their match, Kozma had the gold medal, with Roshchin taking silver. Kozma won the Worlds again in 1966-67 and in 1968, at Mexico City, defended his gold medal with Roshchin again winning silver, and once again, when they met, the match ended in a draw.

The bronze medal in 1964 went to German Wilfried Dietrich, who had won the silver medal in this class in 1956 and 1960. Dietrich was competing in his third Olympics and this was his fourth medal. He would compete again in 1968 and 1972, winning a bronze medal in 1968 in freestyle heavyweight, his fifth medal, which remains, through 2012, an Olympic best for wrestling.
