General elections were held in Denmark on 22 November 1966, although in Greenland the elections were held on 6 December 1966. The Social Democratic Party remained the largest in the Folketing, with 69 of the 179 seats. Voter turnout was 88.6% in Denmark proper, 48.8% in the Faroe Islands and 59.0% in Greenland (where only one of the two constituencies was contested as the other had only one candidate who was elected unopposed).
