The Apostolic Nunciature to Cambodia is an ecclesiastical office of the Catholic Church in Cambodia. It is a diplomatic post of the Holy See, whose representative is called the Apostolic Nuncio with the rank of an ambassador. The title Apostolic Nuncio to Cambodia is held by the prelate appointed Apostolic Nuncio to Thailand; he resides in Thailand.

The Holy See managed its affairs in Cambodia through a Delegation to Indochina established on 20 May 1925.^[1] Pope John XXIII changed its name to the Delegation to Vietnam and Cambodia on 17 June 1964.^[2] Relations were interrupted when the government fell to the Khmer Rouge in 1975. After the restoration of the monarchy in 1993, a new mission was established on 16 July 1994 as the Apostolic Nunciature to the Kingdom of Cambodia.^[3]
