The President of Chile, officially known as the President of the Republic of 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.

An authoritarian military dictatorship ruled Chile for seventeen years, between 11 September 1973 and 11 March 1990. The dictatorship was established after the democratically elected socialist government of Salvador Allende was overthrown in a coup d'état backed by the United States on 11 September 1973. During this time, the country was ruled by a military junta headed by General Augusto Pinochet. The military used the breakdown of democracy and the economic crisis that took place during Allende's presidency to justify its seizure of power. The dictatorship presented its mission as a "national reconstruction". The coup was the result of multiple forces, including pressure from conservative groups, certain political parties, union strikes and other domestic unrest, as well as international factors.
