This article outlines Jewish resistance in Belgium. Communist Jews in Belgium were in the vanguard of partisan resistance but Jews of various political beliefs can be found in throughout the disparate resistance organisations. Half of the Jewish population in Belgium survived the war by going underground either through their own initiative or with the help of the CDJ (Comité de Défense des Juifs)a Belgian resistance organisation, and the local population. The success of rescuing 2,400 children and 10,000 adults was the most important achievement of the Jewish resistance in Belgium.
