Cathédrale du Sacré-Cœur d'Alger (Sacred Heart Cathedral of Algiers) is a Roman Catholic church located in Algiers, Algeria. Completed in 1956, it became the new cathedral in the capital after the Cathedral of Saint Philip of Algiers reconverted into a Muslim Ketchaoua Mosque.{{cite book|last=Borrmans|first=Maurice|title=Tendances et courants de l'islam arabe contemporain: Egypte et Afrique du Nord|url=https://books.google.com/books?id=6dcXAAAAIAAJ|accessdate=20 May 2012|year=1982|publisher=Mainz|language=French|isbn=978-3-459-01471-2|page=251}} The Cathédrale du Sacré-Cœur d'Alger is the cathedral church of the Archdiocese of Algiers.
