1991 Liechtenstein local elections

Local elections were held in Liechtenstein in 1991 to elect the municipal councils and the mayors of the eleven municipalities.

Election system
The municipal councils (German: Gemeinderat) are composed of an even number of councillors plus the mayor (German: Gemeindevorsteher). The number of councillors is determined by population count: 6 councillors for population under 500; 8 councillors for population between 500 and 1,500; 10 councillors for population between 1,500 and 3,000; and 12 councillors for population over 3,000.

Councillors were elected in single multi-member districts, consisting of the municipality's territory, using an open list proportional representation system. Voting was on the basis of universal suffrage in a secret ballot. The mayors were elected in a two-round system. If none of the candidates achieved a majority in the first round, a second round would have been held four weeks later, where the candidate with a plurality would be elected as a mayor.
