2027 Argentine general election

A general election is scheduled to take place in Argentina on 24 October 2027. Voters will elect the president and president of Argentina, members in the Chamber of Deputies and Senate, and the governors of most provinces. Incumbent president Javier Milei is running for reelection for a second term.

Electoral system

President

The election of the president is conducted under the two-round system. A candidate can win the presidency in a single round by either winning over 45% of the vote or if they win 40% of the vote while finishing more than 10 percentage points ahead of the second-place candidate. If no candidate meets either threshold, a runoff takes place between the top two candidates. Voting is compulsory for citizens between 18 and 70 years old. Suffrage is also extended to 16- and 17-year-olds, though without compulsory voting.
While mandatory simultaneous primary elections were established in 2009, it is likely that they will not be carried out for the 2027 general election, as they were suspended for the 2025 legislative election, and multiple political sectors, including Milei, have expressed intent to eliminate them outright.
As per Argentina's electoral law, the first round is expected to take place on October 24, and a potential second round within 30 days, likely on November 21. According to the Constitution of Argentina, the president and vice president can be elected for two consecutive terms. Having been elected in 2023, incumbent president Javier Milei can thus run for re-election in 2027, and he has expressed interest in doing so.
