Stefan Vojislav (Serbian Cyrillic: Стефан Војислав; Greek: Στέφανος Βοϊσθλάβος; fl. 1034–d. 1043) was the Prince of Duklja from 1040 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.
