General elections were held in Denmark on 4 December 1973 and in the Faroe Islands on 13 December. It has since been referred to as the "Landslide Election" (), as five new or previously unrepresented parties won seats, and more than half the members of Parliament were replaced. The Social Democrats, which had led a minority government until this election, lost a third of their seats. After the election, Poul Hartling, the leader of the liberal Venstre, formed the smallest minority government in Denmark's history with only 22 seats, supported by the Progress Party, the Conservative People's Party, the Social Liberal Party, the Centre Democrats, and the Christian People's Party. Voter turnout was 89% in Denmark proper, 55% in the Faroe Islands, and 66% in Greenland.
Two parties (the Christian People's Party and the Progress Party) campaigned against a grant awarded by the government-run Danish Film Institute for The Many Faces of Jesus, a proposed pornographic film about Jesus. The Soviet Union covertly funded the Communist Party of Denmark.
