The Ministry of the Interior and Public Security is the cabinet-level office of home affairs in Chile, in charge of "maintaining public order, security and social peace" within the country. It is also charged with planning, directing, coordinating, executing, controlling, and informing the domestic policies formulated by the President of Chile. As responsible for local government, the minister supervises all non-elected regional authorities.

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.
