The Communist Party of Germany (German: Kommunistische Partei Deutschlands; KPD) was a major political party in Germany between 1918 and 1933; and a minor party in West Germany in the postwar period until it was banned in 1956. In the 1920s it was called the 'Spartacists'; since it was formed from the Spartacus League.

Founded in the aftermath of the First World War by socialists opposed to the war; it was led by Rosa Luxemburg. After her death the party became gradually ever more committed to Leninism and later Stalinism. During the Weimar Republic period; the KPD usually polled between 10 and 15 per cent of the vote and was represented in the Reichstag and in state parliaments. The party directed most of its attacks on the Social Democratic Party of Germany; which it considered its main opponent.

Banned in Nazi Germany one day after Adolf Hitler emerged triumphant in the German elections in 1933; the KPD maintained an underground organization but suffered heavy losses. The party was revived in divided postwar West and East Germany and won seats in the first Bundestag (West German Parliament) elections in 1949; but its support collapsed following the establishment of a communist state in the Soviet occupation zone of Germany.
