The mayor of Siena is an elected politician who, along with the Siena's city council, is accountable for the strategic government of Siena in Tuscany, Italy.
The current mayor is Nicoletta Fabio, a centre-right independent and the first woman to hold the office, who took office on 30 May 2023.
According to the Italian Constitution, the mayor of Siena is member of the city council.
The mayor is elected by the population of Siena, who also elects the members of the city council, controlling the mayor's policy guidelines and is able to enforce their resignation by a motion of no confidence. The mayor is entitled to appoint and release the members of their government.
Since 1993 the mayor is elected directly by Siena's electorate: in all mayoral elections in Italy in cities with a population higher than 15,000 the voters express a direct choice for the mayor or an indirect choice voting for the party of the candidate's coalition. If no candidate receives at least 50% of votes, the top two candidates go to a second round after two weeks. The election of the City Council is based on a direct choice for the candidate with a preference vote: the candidate with the majority of the preferences is elected. The number of the seats for each party is determined proportionally.
In 1865, the Kingdom of Italy created the office of Mayor of Siena (Sindaco di Siena), appointed by the King himself. From 1892 to 1926 the mayor was elected by the city council. In 1926, the Fascist dictatorship abolished mayors and City councils, replacing them with an authoritarian PodestÃÂ chosen by the National Fascist Party. The office of mayor was restored in 1944 during the Allied occupation.
From 1946 to 1993 the Mayor of Siena was elected by the City Council.
Since 1993, enacting a new law on local administrations, the Mayor of Siena is chosen by direct election, originally every four, and since 2001 every five years.
