The Carabineros de Chile (lit. 'Carabiniers of Chile') are the Chilean national gendarmerie, who have jurisdiction over the entire national territory of the Republic of Chile. Created in 1927, their mission is to maintain order and enforce the laws of Chile. They reported to the Ministry of National Defense through the Undersecretary of Carabineros until 2011 when the Ministry of the Interior and Public Security gained full control over them. They are in practice separated fully from the three other military branches by department but still are considered part of the armed forces. Chile also has an investigative police force, the Investigations Police of Chile, also under the Interior and Public Security Ministry; a Maritime Police also exists for patrol of Chile's coastline.

The origins of the Carabiniers can be traced back to night watchmen such as the Dragones de la Reina (Queen's Dragoons) (created in 1758 and later renamed the Dragoons of Chile in 1812) and other organizations that fulfilled functions such as the watch and local policing.

Later, cities such as Santiago and Valparaíso created their own city police forces. In 1881 the Rural Police (Policía Rural) was created for the rural areas of the country. However, the main problem with these police services was that they were dependent on local authorities for day-to-day decision making. This led to local officials abusing this power for their own political ends. In 1896 the Fiscal Police (Policía Fiscal) was created to serve the cities.

The first policing organization with the name "Carabiniers" was the Corps of Carabineros, in Spanish Cuerpo de Carabineros (with similar meaning as the Italian Carabinieri), formed in 1903 to bring law and order to the conflictive Araucanía region of Southern Chile (then much larger than today's region), formerly the Gendarme Corps, which would later be merged with the Army's 5th Carabineros Regiment and the Rural Police. The Carabinier Regiment was then a Chilean Army unit, thus the reason why the Carabineros of today sport military ranks and insignia. In 1908 the Carabineros' School (Escuela de Carabineros, currently located in Providencia) was created, which until 1935 trained all officers and non-commissioned sworn personnel.

On April 27, 1927, President Carlos Ibáñez del Campo merged the Fiscal Police, the Rural Police, and the existing Corps of Carabineros to form the Carabineros de Chile, one unified, paramilitary and national security institution under the direction of the national government. The organization still carries the name given to it by Ibáñez, who became the Carabineros' first Director General. In 1929 its official coat of arms – two white crossed carbines in a green shield – was formally adopted. The service in 1930 became one of the pioneer mobile police forces in Latin America. By 1933 the Investigations Police of Chile was created in the basis of the investigations service. The roots of today's NCO School began in 1934 when in Santiago's Macul commune, the service's mounted command began training NCOs and enlisted personnel independently. In 1939 the service received its own staff college, the Police Sciences Academy, and its own equestrian demonstration unit, the Cuadro Verde, and the mounted training squadron began the present day NCO School in 1951.

The Air Operations Prefecture, the air arm of the service, was raised in 1960.

In 1962 it became the first Chilean uniformed service to include women in its ranks. The next year, the Children and Fatherland Foundation was formed as its social responsibility arm for troubled kids and preteens.

In 1973, the Carabineros, headed by General Cesar Mendoza, later appointed Director General, joined the Chilean coup of 1973 under the lead of the Army, Navy and Air Force leaders, that overthrew President Salvador Allende. As such, the Carabineros' commander was a formal member of the Military Government Junta, as well as members of the institution taking on administrative roles, such as being in charge of the Ministry of Education.
