# Judo at the 2004 Summer Paralympics – Men's 81 kg

The Men's up to 81 kg judo competition at the 2004 Summer Paralympics was held on 19 September at the Ano Liossia Olympic Hall.
The tournament bracket consisted of a single-elimination contest culminating in a gold medal match. There was also a repechage to determine the winners of the two bronze medals. Each judoka who had lost to a semifinalist competed in the repechage. The two judokas who lost in the semifinals faced the winner of the opposite half of the bracket's repechage in bronze medal bouts.
The event was won by Cyril Jonard, representing France.

## Results

The four digits represent scores of ippon, waza-ari, yuko and koka (which was still used at the time). A letter indicates a penalty of shido, chui, keikoku or hansoku make, which (at the time) also registered a score of koka, yuko, waza-ari or ippon, respectively, to the opponent. Penalties are escalated, thus 2 shido = chui, 3 shido = keikoku, 4 shido = hansoku make, save that a penalty of hansoku make direct results in exclusion from the remainder of the competition, while if it results from escalation it does not.
