Date 6 August 1984 — 16:00-20:00
StatusOlympic
LocationEagle's Nest Arena, California State University at Los Angeles, Los Angeles, California
Participants31 from 31 countries
FormatTwo single-elimination pools, with winner of each pool advanced to the final. All judoka losing to the winner of each pool advanced to repêchage pools, with the winners of the repêchage pools earning bronze medals.

The defending champion was Italy’s Ezio Gamba, who had placed second at the 1983 World Championships to Japan’s Hidetoshi Nakanishi. They were the two favorites and this class was one on which the boycott had minimal effect. In the first round, Nakanishi had difficulty with the Senegalese Ibrahima Diallo. Nakanishi won but broke a rib in the process and would not win a medal. Gamba started out with a tough match against Serge Dyot (FRA), the 1984 European runner-up. But Gamba had little trouble, Dyot eventually submitting – twice, as the referee did not notice the first submission. Gamba made the final where he faced Korean An Byeong-Geun. Gamba was favored but An scored two kokas early on, and was able to hold off Gamba to win the gold medal.
