The Roman Catholic Archdiocese of Bar is an ecclesiastical territory or diocese of the Roman Catholic Church in Montenegro. It is centred in the city of Bar (Italian Antivari). It was erected as a diocese in the 9th century and elevated to an archdiocese in 1089. The Archbishopric was by Pope's decree abolished some time after 1140, until it was restored by the Serbian medieval Nemanjić dynasty in 1199.
