Chile begins a new electoral cycle on November 16 with the 2025 parliamentary elections, electing representatives and senators who will form the National Congress for the next four years. These elections are taking place in parallel with the first round of the presidential elections, which determines the two presidential candidates who will run in a final second round, scheduled to be held on December 14.
In these elections, the 155 representatives and 23 senators will be renewed. In the case of the Senate, where the office lasts eight years, representatives are elected to the office in the regions of Arica, Parinacota, Tarapaca, Atacama, Valparaíso, Maule, La Araucanía and Aysín. In the rest of Chile, voting is limited to the president and his vice president.
Parliamentary elections operate on the Döndt system, in which seats are distributed through lists. This forces political parties to form coalitions and agreements to obtain the largest number of elected representatives. Five agreements have been recorded between some of the 24 communities established before the electoral service in Chile (Servel). Other communities decided to present themselves without a list or outside the agreement.
Who are the candidates for the offices of Representatives and Senate?
On September 1, Serville published the full list of all parliamentary candidates whose registrations had been accepted. The list of candidates for the position of representatives consists of 1,091 confirmed applications. The number of accepted candidates for Senate membership reaches 130. The full list is available in Servel’s official search engine. There users can consult by region and constituency.
Confirmed charters and parties
Exchange to Chile
Republican Party; The Social Christian Party (PSC) and the National Libertarian Party (PNL), representing the Chilean far-right, were the first to register an agreement for the parliamentary elections. On August 8, representatives of the formations before Serville ratified the creation of a pact called Cambio por Chile. The groups that make up this coalition support different candidates in the presidential elections: the Republicans and the Christian Socialists support José Antonio Cast, while the liberals promote the candidacy of Johannes Kaiser. With the ratification of this charter, the far right has blown its bridges with Chile Vamos, the traditional right-wing coalition, which promoted the presentation of a single opposition list to confront the ruling leftist party.
Unity for Chile
The center-left and left-wing parties that are part of President Gabriel Buric’s administration achieved unity after primaries that gave the winner to communist presidential candidate Janet Jara, who remained the sole representative of a coalition called Unity for Chile. One of the goals of this confluence was also to build a single list for the parliamentary elections, which would allow progressivism to resist any possible electoral attack by the right. The desired unity was not achieved, so progressivism would be presented in two charters. One of them consists mainly of formations big The sector, consisting of the frontal amplio (FA); Communist Party (PC); Socialist Party (PS); Party for Democracy (PPD); The Radical Party (PR) and the Liberal Party (PL), were joined by the Christian Democracy (DC), which was not part of the original government coalition.
Great and United Chile
Chile Vamos, the traditional right-wing coalition that forms the National Renewal (RN); the Independent Democratic Union (UDI); The Political Development Party (Evopoli) sought – in vain – to unite all sectors opposed to Buric’s government to present a single parliamentary list. After the failure of negotiations with the far right, the coalition supporting presidential candidate Evelyn Mathi began talks to include centrist sectors. The agreement sought to incorporate the Democratic Party into its list, with which an agreement was reached. The alliance was called “Chile Grande y Unidos.”
Greens, regionalists and humanists
The Regional Green Social Union (FRVS) and Action Humanitarian (AH), two of the smallest groups in the ruling party, decided to break away from the rest of their coalition allies and present themselves on a separate list. The parties of this list confirmed that despite their departure from the official electoral bloc, they maintain their support for presidential candidate Janet Jara.
Left is a famous animal and human ecologist
The Humanist Party (PH) and the Equality Party (PI), two radical left-wing formations splintering from the ruling party, registered on the left-wing list of popular environmentalists Animal and Humane. The charter is a continuation of the Popular Eco-Left Alliance, which was introduced in the 2024 municipal elections.
Parties outside the Charter
As for the rest of the political parties, they have known to compete alone outside the list as a strategy to compete in the parliamentary elections. The formations that took this route are Amarillos por Chili; People’s Party (PDG) – which supports presidential candidate Franco Parisi -; the Party of Green Environmentalists (PEV); Popular Party (PP); People’s Green Alliance Party (PAVP) and Workers’ Revolutionary Party (PTR).
