The president of Chile (Spanish: Presidente de Chile), officially the president of the Republic of Chile (Spanish: Presidente de la República de Chile), is the head of state and head of government of the Republic of Chile. The president is responsible for both government administration and state administration. Although its role and significance have changed over time, and its position and relations with other actors in the national political organization have also evolved, it remains one of the most prominent political offices in the country. It is also considered one of the key institutions that form the "Historic Constitution of Chile," and is crucial to the country's political stability.

Under the current Constitution, adopted in 1980, the president serves a four-year term and is not eligible for immediate re-election. The shorter term (previously it was six years) allows for synchronized parliamentary and presidential elections. The president's official seat is the La Moneda Palace in the capital Santiago.

Michelle Bachelet was the first female president of Chile and served twice, from 2006 to 2010 and again from 2014 to 2018. Gabriel Boric is the current president, having won the 2021 Chilean general election and taken office on 11 March 2022.

The origins of Chile as a nation can be traced to 1541, when it was separated from the existing Viceroyalty of Peru by King Charles I, creating the new Kingdom of Chile. The head of state continued to be the king, but he was represented locally by the Royal Governor.

The Constitution of 1980, with its 2005 amendment, outlines the qualifications for becoming president. To be eligible, the individual must be a natural-born Chilean citizen or born abroad to Chilean parents or grandparents. They must also be at least 35 years old and meet all the requirements for becoming a Senator.

In addition, the president must have the right to vote as a fully Chilean citizen, which includes being at least 18 years of age, not having been sentenced to a severe punishment, not having lost the right to vote due to insanity, not having been tried or condemned for a serious crime or terrorist conduct, nor condemned by the Constitutional Court under Article 8 of the Chilean Constitution.

Article 26 detail the electoral requirements. The president shall be elected by direct ballot, with an absolute majority of the votes validly cast. A two-round system is used. In order to win the election in the first round, the winning candidate's party must receive more than 50 percent of the valid votes leaving out of the count blank and spoiled votes.

The election shall be held the third Sunday of November of the year immediately before the end of the administration of the president then holding office. Should there be more than two candidates in the presidential election, none of them obtaining more than half of the votes validly cast, a new election shall be held. The second election ("balloting"), in the manner determined by law, shall be held the fourth Sunday after the first election, limited to the two candidates with the highest relative majorities. Then, the candidate with the majority of valid votes in that round is elected president. Previously, under the 1925 constitution, the Congress of Chile elected the president in the run-off, including (notably) in the 1970 Chilean presidential election.
