Middleweight (≤86 kilograms), Men

Date	8 August 1984 — 16:00
Status	Olympic
Location	Eagle's Nest Arena, California State University at Los Angeles, Los Angeles, California
Participants	29 from 29 countries
Format	Two 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 1983 World Champion was Detlef Ultsch (GDR), while earlier in 1984, Soviet Vitaly Pesnyak had defeated East German Michael Borawski for the European title. Because of the boycott, none of them were in Los Angeles. But the other three medalists from the 1983 Worlds were present – Bob Berland (USA), Fabien Canu (FRA), and Japan’s Seiki Nose. Nose was a 6th Dan, the highest grade in the 1984 judo tournament. In the end, one judoka dominated the class, but it was not a favorite. Peter Seisenbacher, an Austrian goldsmith, won all five of his matches before the time limit, taking 11:05 to win his gold medal. In the final he fought Berland, winning by ippon with ashi-guruma in 2:26.
