The Eparchy of Zahumlje, Herzegovina and the Littoral () is an eparchy (diocese) of the Serbian Orthodox Church with its seat in Mostar, Bosnia and Herzegovina. It has jurisdiction over the region of Herzegovina, the littoral region of southern Dalmatia in Croatia and a small part of Montenegro. Since 2018, the bishop of Zahumlje and Herzegovina has been Dimitrije Rađenović. History Ecclesiastical background The region was under the Eastern Orthodox Metropolitanate of Dyrrachium, which in turn was under the Ecumenical Patriarchate of Constantinople or the Archbishopric of Bar. In 1089, the see of Trebinje (Travunia) was briefly theoretically under the jurisdiction of the Archbishopric of Bar.
