Apostolic Nunciature to Mauritania

The Apostolic Nunciature to Mauritania is the diplomatic mission of the Holy See to Mauritania. The Apostolic Nuncio to Mauritania is an ecclesiastical office of the Catholic Church in Mauritania, with the rank of an ambassador. The nuncio serves both as the ambassador of the Holy See to the Republic of Mauritania and as the point-of-contact between the Catholic hierarchy in Mauritania and the pope.

Since its creation in 1973, the post of Nuncio to Mauritania has been held by the archbishop who is Nuncio to Senegal; the Nuncio to Mauritania resides in Dakar, Senegal.

In 1948, the Holy See established the Delegation to Dakar led by Marcel-François Lefebvre to represent its interests in French colonial Africa. Following the decolonization of the region, the title of that position was changed to Apostolic Delegate to Western Africa on 23 September 1960 and given responsibility for Senegal, Upper Volta, Côte d'Ivoire, Dahomey (Benin), Guinea, Mauritania, Niger, Sudan, Togo, Ghana, Gambia, and Sierra Leone. Over the next decade, as the Vatican established relationships with individual countries, country-specific offices were created, including the Delegations to Guinea, Togo, Mali, and Mauritania on 21 May 1973.
