Republican Party of Chile

The Republican Party of Chile (Spanish: Partido Republicano de Chile, officially abbreviated as PRCh, and commonly abbreviated in the media as REP or, less frequently, PRep) is a right-wing and conservative political party founded in Chile in 2019 by José Antonio Kast, who led the party until his resignation in 2026 following his inauguration as president of Chile.

The party is socially conservative and in favour of a liberal social market economy. The party opposes abortion, euthanasia, same-sex marriage, proposals for a new Chilean constitution, and advocates a tough approach to law and order, gang violence, political corruption and illegal immigration into Chile. Economically, it advocates a largely free-market economy with strong protections for private property, low taxes, lower government spending, and incentives for entrepreneurship, however it also embraces a social market economy.

The party gained visibility during the political upheavals that followed the 2019 Social Outburst and the subsequent constitutional reform process, initially operating from a position of disadvantage within the Chilean right. Kast placed first in the initial round of the 2021 general election, building on a limited but defined electoral base and securing approximately 28 percent of the vote.

In the 2023 Constitutional Council elections, the Republicans won the largest share of seats of any political group and played a leading role in drafting a proposed new constitution of Chile which was rejected in a referendum in December 2023. Kast led polls for the presidential run-off in the 2025 Chilean general election, and won the presidency on 14 December 2025.
