Catherine Jacques (born 28 September 1979, in Merksem) is a female Belgian judoka who competed in the middleweight category (70 kg). She is a multiple-time national champion, and a four-time bronze medalist for her category at the European Judo Championships. At the 2004 Summer Olympics in Athens, Jacques missed out of the Olympic podium in the women's 70 kg category, after she was defeated by Germany's Annett Böhm, who scored an ippon within thirty-eight seconds, in the bronze medal match. She was able to fight back against her opponent for a rematch to capture the bronze medal, this time at the 2005 World Judo Championships in Cairo, Egypt.
