Voters will be electing the next President, all 155-members of the lower house Chamber of Deputies and 23 out of 50 senators in the upper house Senate.
Chile reintroduced compulsory voting in 2023.
If no presidential candidate secures more than 50% of the vote in the first round, the two leading contenders will head to a runoff on 14 December 2025. The new president will take office on 11 March 2026 and serve a four-year term.
Incumbent President Gabriel Boric of the Unity of Chile coalition is constitutionally barred from seeking a consecutive second term and will be replaced by Jeannette Jara as the presidential candidate.
The other candidates are José Antonio Kast of the Republican Party; Evelyn Matthei of the Great and United Chile coalition; Johannes Kaiser of the National Libertarian Party; and Franco Parisi of the Party of the People.
Chile has a bicameral Congress. Members of the Chamber of Deputies serve four-year terms and Senate members serve eight-year terms.
The country has a population of around 19.9 million and 15 million registered voters. In the 2021 election, voter turnout was 47%.
