The 2021 Turin municipal election took place in Turin, Italy, on 3 and 4 October 2021, to elect the mayor and the 38 members of the Turin city council. Since no mayoral candidate won a majority of votes on the first round, a runoff was held on 17 and 18 October 2021. The second round was won by the centre-left coalition candidate Stefano Lo Russo, member of the Democratic Party, who was officially inaugurated as new mayor of Turin on 27 October 2021. The incumbent mayor of Turin, Chiara Appendino of the Five Star Movement, did not run for re-election.
