The Committee for the Defence of Jews (French: Comité de Défense des Juifs, or CDJ; Dutch: Joods Verdedigingscomiteit, JVD) was a group within the Belgian Resistance, affiliated to the Front de l'Indépendance, founded by the Jewish Communist Hertz Jospa and his wife Have Groisman (Yvonne Jospa) of Solidarité juive in September 1942.

These members formed an effective committee and came from all political and religious horizons, overcoming their divergent views to unite for the sake of saving Jewish children.

The CDJ was also involved in other aspects of the resistance, producing the clandestine publications such as the Yiddish periodical Unser Wort ("Our Word"[4]).

The CDJ also functioned as a national organisation in the field of social services.

As a result of its actions, it is thought that around 3,000 Jews were rescued from deportation.
