The Diocese of Copenhagen is a Latin Church ecclesiastical territory or diocese of the Catholic Church named after its episcopal see, the Danish national capital, Copenhagen and covers all Denmark. As in neighbouring provinces, none of the pre-Reformation bishoprics were re-established after Lutheranism became the new official state church in the 16th century). The diocese also covers two Danish overseas possessions, the Faroe Islands and Greenland. It is estimated that 36,000 (0.7%) out of the 5,516,597 inhabitants of the diocesan territory are Catholics.
