Orlando Letelier, Chilean economist and politician, Minister of Foreign Affairs for Chile (born 1932)

Marcos Orlando Letelier del Solar was a Chilean economist, politician, and diplomat during the presidency of Salvador Allende. A refugee from the military dictatorship of General Augusto Pinochet, Letelier accepted several academic positions in Washington D.C. after his exile from Chile. In 1976, agents of Dirección de Inteligencia Nacional (DINA), the Pinochet regime's secret police, assassinated Letelier in Washington in a car bombing. The agents had been working in collaboration with members of the Coordination of United Revolutionary Organizations, an anti-Castro militant group.

The Ministry of Foreign Affairs of Chile is the cabinet-level administrative office in charge of planning, directing, coordinating, executing, controlling and informing the foreign policy formulated by the President of Chile. It is located in the Edificio José Miguel Carrera at Plaza de la Constitución, in downtown Santiago.
