The Constitution of Belgium (Dutch: Belgische Grondwet; French: Constitution belge; German: Verfassung Belgiens) dates back to 1831. Since then Belgium has been a parliamentary monarchy that applies the principles of ministerial responsibility for the government policy and the Trias Politica.

The most recent major change to the constitution was the introduction of the Court of Arbitration, whose competencies were expanded by a special law of 2003, to include Title II (Articles 8 to 32), and the Articles 170, 172 and 191 of the Constitution. The Court developed into a constitutional court; in May 2007 it was formally redesignated as the Constitutional Court. This court has the authority to examine whether a law or a decree is in compliance with Title II and Articles 170, 172 and 191.
