The Apostolic Nunciature to Yugoslavia was an ecclesiastical office of the Catholic Church in Yugoslavia. It was a diplomatic post of the Holy See, whose representative is called the Apostolic Nuncio with the rank of an ambassador.
The Kingdom of Serbs, Croats and Slovenes was created in the aftermath of the First World War; its name was changed to Yugoslavia in 1929. The Nunciature to Yugoslavia was created in 1921 and ended with the overthrow of the Yugoslav monarchy and the creation of a Communist government at the end of World War II. Following the dissolution of the Soviet Union and the Warsaw Pact, Yugoslavia and the Holy See reestablished relations in 1976. As Yugoslavia subdivided into a group of successor states, each with its own diplomatic relations with the Holy See, the responsibilities of the Nunciature to Yugoslavia shrank until the last Apostolic Nuncio to Yugoslavia was appointed in 2000 when the nunciature in Belgrade was located in the Federation of Montenegro and Serbia, which then dissolved in 2006, transforming the nunciature in Belgrade into the Apostolic Nunciature to Serbia.
