Diplomatic missions of the Holy See

This is a list of diplomatic missions of the Holy See. Since the fifth century, long before the founding of the Vatican City State in 1929, papal envoys (now known as nuncios) have represented the Holy See to foreign potentates. Additionally, papal representatives known not as nuncios but as apostolic delegates ensure contact between the Holy See and the Catholic Church in countries that do not have diplomatic relations with the Holy See.

At present, there is one residential apostolic delegate, for Jerusalem and Palestine, as well as non-residential ones for six countries (Brunei, Burma, Laos, Mauritania, Somalia, Vietnam) and for the territories and countries without diplomatic relations in three regions (Arabian Peninsula, the Caribbean, the Pacific Ocean). The head of the apostolic delegation for Vietnam is described in the Annuario Pontificio not as an apostolic delegate but generically as a papal representative. In keeping with the "one China" policy, no representative, whether nuncio or apostolic delegate, is appointed for mainland China, and the Holy See is represented in Taipei by an apostolic nunciature, headed not by a nuncio, but only by a chargé d'affaires. Many countries, such as the United States, for which apostolic delegates were once appointed, now have nuncios.

In addition to the countries mentioned above as having apostolic delegations, the following nations do not have diplomatic relations with the Holy See: Afghanistan, Bhutan, People's Republic of China, North Korea, Oman, Saudi Arabia, and Tuvalu.
