The Constitution of the German Reich (German: Die Verfassung des Deutschen Reichs), usually known as the Weimar Constitution (Weimarer Verfassung) was the constitution that governed Germany during the Weimar Republic (1919–1933). The constitution declared Germany to be a democratic parliamentary republic with a legislature elected under proportional representation. Universal suffrage was established, with a minimum voting age of 20. The constitution technically remained in effect throughout the existence of the Third Reich from 1933 to 1945.

The constitution's title was the same as the Constitution of the German Empire that preceded it. The German state's official name was Deutsches Reich until the adoption of the 1949 Basic Law.
