Radoslav was the Prince of Duklja from c. 1146 to c. 1149. As the oldest son, he succeeded as ruler of Duklja after the death of his father, Gradinja in c. 1146. He was installed by Manuel I Komnenos upon a visit to Constantinople to pay homage to the Emperor. Unlike his father who was a titular king, Radoslav had the title of Prince (knez). Radoslav began his rule at a time when the Serbs of Raška had ambitions towards Duklja.
