The 2023 Liechtenstein local elections were held on 5 March and 2 April to elect the municipal councils and the mayors of the eleven municipalities of Liechtenstein.
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 or 8 councillors for population 1,500, 8 or 10 councillors for population between 1,500 and 3,000, and 10 or 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. As two of the municipalities saw none of the candidates achieving a majority in the first round, a second round was held four weeks later, where the candidates with a plurality were elected as a mayor.
