The Archdiocese of Port-au-Prince (erected 3 October 1861) is a metropolitan archdiocese, responsible for the suffragan dioceses of Jacmel, Jérémie, Anse-à-Veau and Miragoâne and Les Cayes.

The archdiocese was a vacant see following the death of Archbishop Joseph Serge Miot, who was one of the many casualties of the 12 January 2010 earthquake when the Archdiocesan Chancery building collapsed. The archdiocese's chancellor was also reportedly killed.

On the one-year anniversary of the disaster, Pope Benedict XVI named Guire Poulard - who had been the Bishop of Les Cayes - as the new Archbishop of Port-au-Prince. At the same time he named Glandas Marie Erick Toussaint as the auxiliary Bishop of the Archdiocese.
