[File:Greek legislative election 1981.svg|thumb|right|300px|Distribution of parliament seats after the 1981 elections. ]] Parliamentary elections were held in Greece on Sunday, 18 October 1981. The Panhellenic Socialist Movement (PASOK), led by Andreas Papandreou, faced New Democracy, led by Georgios Rallis. Papandreou achieved a landslide and PASOK formed the first socialist government in the history of Greece (in 1963 Centrists had formed a government under the leadership of George Papandreou, Andreas' father, but their party, Center Union, was not a socialist party but a centrist, social-liberal one).
