2020 San Marino local elections

Active and passive suffrage was entitled to resident Sammarineses over 18 years old, as well as foreingers having resided in San Marino for at least 10 years. Voters elected the mayor (Italian: capitano di castello) and the municipal council (giunta di castello). The number of councillors is defined according to the population:

Candidates for the municipal councils ran on lists led by a mayoral candidate. Voters elected a list and were allowed to give up to two preferential votes. Seats were allocated with the d'Hondt method if the winner had obtained at least 62.5% of the votes. Otherwise, five seats would have been allocated to the winning party (four seats if the council had six members) and the rest of the seats would have been allocated using the d'Hondt method to the rest of the parties. The mayoral candidate of the winning list was proclaimed mayor.

In case of a tie for the first position, a second round would have taken place between the two mayoral candidates. In case of a tie in the second round, the youngest candidate would be elected. In the municipalities where only one list contested the election, the election was considered valid if the turnout was over 35%.[3]

Overall turnout was 41.1%, 4.7pp lower than in 2014. The highest turnout was recorded in the smallest municipalities: Chiesanuova and Montegiardino.
