2021 Peruvian general election

General elections were held in Peru on 11 April 2021. The presidential election, which determined the president and the vice presidents, required a run-off between the two top candidates, which was held on 6 June. The congressional elections determined the composition of the Congress of Peru, with all 130 seats contested.

Pedro Castillo, a member of the left-wing Free Peru party, received the most votes in the first round. In the second round he faced Keiko Fujimori, the leader of the right-wing populist Popular Force who had previously lost the run-offs of the 2011 and the 2016 elections. Both candidates were surprise contenders; Fujimori had initially been discounted due to her preventive imprisonment for a year, while Castillo was a political newcomer who was previously unknown to the public.

The official count of the second round by the National Office of Electoral Processes indicated that Castillo had won with 50.13% of the vote, a lead of 44,263 over Fujimori. However, the declaration of an official outcome certifying the result by the National Jury of Elections was delayed following accusations of electoral fraud by opposition politicians. Castillo was ultimately named president-elect by the National Jury of Elections on 19 July, and was inaugurated on 28 July. The opposition gained control of Congress.

The President of Peru is elected using the two-round system. The first round voting was held on 11 April and allows eligible voters to vote for any viable presidential candidate. The top two candidates who receive a plurality of the vote proceed to the run-off election, which took place on 6 June. The winner of the run-off election and the presidential election is the candidate who receives a plurality of the popular vote. However, if in the first round the candidate who is in the first place already gets more than 50% of the popular vote, that candidate will automatically win the election and a run-off election will no longer be needed.

The 130 members of Congress are elected in 27 multi-member constituencies using open list proportional representation. To enter Congress, parties must either cross the 5% electoral threshold at the national level, or win at least seven seats in one constituency. Seats are allocated using the D'Hondt method.

Peru has five places in the Andean Parliament, elected using a common constituency by open-list.

President Martín Vizcarra initially presented legislation that would set the conditions for a snap election in 2020. If successful, Vizcarra would not be eligible for re-election. The 2020 proposed Peruvian general election would be held on 11 April 2020, to elect a new President of the Republic of Peru, along with 130 congressmen of the Congress of Peru. It was eventually decided to be held on 26 January 2020. Opposition lawmakers condemned Vizcarra's proposal, defending the practice of five-year terms. This constitutional reform was rejected.

The 2021 Peruvian general election were held on 11 April 2021, to elect the president of the Republic of Peru, two vice presidents of the same party, 130 congressmen of the Congress of Peru and 5 Andean parliamentarians for a five-year term from 2021 to 2026.
