# Judo at the 2012 Summer Olympics – Women's 48 kg

Women's 48 kg competition in judo at the 2012 Summer Olympics occurred at ExCeL London in London.
The gold and silver medals were determined by a single-elimination tournament, with the winner of the final taking gold and the loser receiving silver. Judo events awarded two bronze medals. Quarterfinal losers competed in a repechage match for the right to face a semifinal loser for a bronze medal (that is, the judokas defeated in quarterfinals A and B competed against each other, with the winner of that match facing the semifinal loser from the other half of the bracket).
