The Apostolic Nunciature to the Republic of Mexico is an ecclesiastical office of the Roman Catholic Church in Mexico. It is a diplomatic post of the Holy See, whose representative is called the Apostolic Nuncio with the rank of ambassador.
Before 1992 the office was an Apostolic Delegation, without diplomatic status: its head was accredited to the Catholic Church in the country but not to the government.
