The House of Vojislavljević was a Serbian medieval dynasty, named after archon Stefan Vojislav, who wrested the polities of Duklja, Travunia, Zahumlje, inner Serbia and Bosnia from the Byzantines in the mid-11th century. His successors, kings Mihailo I Vojislavljević and Constantine Bodin expanded and consolidated the state. During the 12th century, the main line of the Vojislavljević family was ousted by their cadet branch, the Vukanović. (which became the Nemanjić dynasty), in the late 12th century.

Stefan Vojislav was the Prince of Duklja from 1018 to 1043. Beginning in the year 1018, he served as a Byzantine governor, until 1034 when he led an unsuccessful revolt that landed him in a prison at Constantinople. He managed to escape and returned home, this time successfully gaining the independence of his statelet and expanding his rule over southern Dalmatia and its hinterland. He is the eponymous founder of the Vojislavljević dynasty.
