The middleweight competition was the fourth-highest weight class featured in amateur boxing at the 2008 Summer Olympics, and was held at the Workers Indoor Arena, Beijing China.

Middleweights were limited to a maximum of 75 kilograms in body mass.

Like all Olympic boxing events, the competition was a straight single-elimination tournament.

Both semifinal losers are awarded bronze medals, so no boxers compete again after their first loss.

Punches are scored only if the white area on the front of the glove makes full contact with the front of the head or torso of the opponent.
