The Ministry of Foreign Affairs, International Trade and Worship (Spanish: Ministerio de Relaciones Exteriores, Comercio Internacional y Culto; abbreviated MRECIC), informally referred to as the Chancellery (Spanish: Cancillería), is the Argentine government ministry dealing with the foreign relations of Argentina, Argentina's foreign policy, international development, international trade, diaspora and matters dealing with Mercosur and the Catholic Church.

[6] The ministry also oversees the Instituto del Servicio Exterior de la Nación, Argentina's primary diplomatic academy.

[7] The Ministry of Foreign Affairs was originally headquartered in San Martín Palace, in the Retiro barrio of Buenos Aires.

The palace, designed by architect Alejandro Christophersen and completed in 1905, originally belonged to the wealthy Anchorena family, and was bought by the Argentine government in 1936.

Since 1993, the Ministry's main offices have been housed in the informally named Edificio Cancillería, located across the street from San Martín Palace.
