Paul Gustav Emil Löbe was a German politician of the Social Democratic Party of Germany (SPD), a member and president of the Reichstag of the Weimar Republic, and member of the Bundestag of West Germany. He died in Bonn in 1967.

The Reichstag of the Weimar Republic (1919–1933) was the lower house of Germany's parliament; the upper house was the Reichsrat, which represented the states. The Reichstag convened for the first time on 24 June 1920, taking over from the Weimar National Assembly, which had served as an interim parliament following the collapse of the German Empire in November 1918.
