2021 Chilean general election

General elections were held in Chile on 21 November 2021, including presidential, parliamentary and regional elections. Voters went to the polls to elect a president to serve a four-year term, 27 of 50 members of the Senate to serve an eight-year term, all 155 members of the Chamber of Deputies to serve a four-year term and all 302 members of the regional boards to serve a three-year term. Following an electoral reform in 2015, the Senate increased its membership from 38 to 43 in 2017 and grew to its full size of 50 seats after this election.

Despite narrowly trailing conservative candidate José Antonio Kast in the first round of the presidential election, leftist candidate Gabriel Boric emerged as the winner of the second round with 56% of the vote, a larger margin than predicted by opinion polls. Kast conceded defeat shortly after voting ended. At the age of 35, Boric became the youngest president ever elected in Chile and also set a record for receiving the highest number of votes in Chilean history. The turnout in the second round increased to 56%, the highest since voting became voluntary in Chile in 2013.

In the parliamentary elections the center-right coalition Chile Podemos Más remained the largest bloc in both chambers and increased their number of senators, despite seeing their vote share fall by more than 10 percentage points compared to the previous election. On the left, the new coalition Apruebo Dignidad saw gains at the expense of the center-left New Social Pact (NPS), becoming the second largest bloc in the Chamber of Deputies. However, NPS won more seats in the Senate. New parties, including the far-right Republican Party and the populist Party of the People, also gained several seats. Consequently, the newly elected Congress was split evenly between the combined left and right, with the non-aligned congresspeople holding the balance of power.

On 11 March 2022 all the newly elected authorities, including president-elect Boric, took office.
