Pomorje (Serbian Cyrillic: Поморје), also known (in plural) as the Lands of Pomorje (Serbian Cyrillic: Поморске земље), is a medieval term, used to designate several maritime regions of Upper Dalmatia and its hinterland, that at the end of the 12th century, during the reign of Stefan Nemanja (1166–1196), became part of the Grand Principality of Serbia, and remained part of the medieval Kingdom of Serbia, whose rulers were styled with the title: "crowned king and autocrat of all Serbian and coastal lands".
