1966 Liechtenstein general election

General elections were held in Liechtenstein on 6 February 1966. The Progressive Citizens' Party won eight of the 15 seats in the Landtag, but remained in coalition with the Patriotic Union. Voter turnout was 95.6%, although only male citizens were allowed to vote.

Electoral system

The 15 members of the Landtag were elected by open list proportional representation from two constituencies, Oberland with 9 seats and Unterland with 6 seats. The electoral threshold of 18% had been replaced by a basic mandate system due to the Liechtenstein constitutional court ruling it unconstitutional in 1962. The election used a majority clause, where the party with the most votes also received the most seats. Only male citizens were eligible to vote.
