The 2007 World Judo Championships are the 25th edition of the Judo World Championships, and were held at the Rio Olympic Arena, usually called Arena Multiuso, that was built for the 2007 Pan-American Games, in Jacarepaguá, Rio de Janeiro, Brazil from September 13 to September 16, 2007.

The competition gathered the sport's top athletes in Rio de Janeiro, with only a few exceptions, due to injuries.

Among the high-profile injured judokas that were unable to participate were Brazil's Flávio Canto, bronze medallist in the -81 kg category at the 2004 Summer Olympic Games, who tore a ligament in his right elbow during the 2007 Pan American Games (during the event, Canto participated as a commentator for the Brazilian paid sports channel, SporTV); and Japan's Tadahiro Nomura, the three-time Olympic champion and heavy favorite in the -60 kg category was forced to withdraw only a few weeks before the event due to injury (his replacement was able to place 7th in the competition).

Marius Vizer was elected by the attending representatives to replace Yung Sang Park, the current president.

In the men's side, Brazil's Tiago Camilo, who won in the -81 kg category by defeating all opponents by ippon (the perfect score, which ends the match automatically), was selected; and in the women's side, North Korea's Kye Sun-hui, who won in the -57 kg category, was chosen as best female athlete in the competition.
