According to the Institute for Jewish Policy Research, there were just 29,000 self-identified Jews in Belgium, accounting for 0.25% of the 2022 total population. The majority dwell in Brussels or Antwerp, the country's two largest cities. While most Jews in the largely French-speaking capital of Brussels are secular, Antwerp, a Dutch-speaking port city, boasted one of Europe's largest ultra-Orthodox Jewish populations as well as the largest Hasidic population, in the world.
The main representative body of the Belgian Jewish community is the Coordinating Committee of Belgian Jewish Organizations (Comité de Coordination des Communautés Juives de Belgique) – the Belgian affiliate of the World Jewish Congress.
