The Archdiocese of Paris is a Latin Church ecclesiastical jurisdiction or archdiocese of the Catholic Church in France. It is one of twenty-three archdioceses in France. The original diocese is traditionally thought to have been created in the 3rd century by St. Denis and corresponded with the Civitas Parisiorum; it was elevated to an archdiocese on October 20, 1622. Before that date the bishops were suffragan to the archbishops of Sens.
