These elections were originally scheduled for 25 October 2020, but the COVID-19 pandemic changed the entire election schedule in Chile, moving the 2020 national plebiscite from 26 April to 25 October. The municipal elections were moved then to 11 April 2021, extending the term of the mayors elected in the previous election.^[2] Due to the pandemic, the municipal elections (and the concurring other elections) were extended to two days (10 and 11 April) to avoid agglomerations, becoming the first election in Chile to be held in more than one day. Finally, the elections were again postponed to 15 and 16 May 2021 due to a rise in the cases of COVID-19.^[1]
