Constantine Bodin (Константин Бодин; fl. 1072-1108) was a ruler of Duklja, the second, although titular, King of Duklja from 1081 to 1101, succeeding his father, King Michael. Prior to becoming a ruler of Duklja he was crowned Bulgarian Emperor by name Petar III (Петър III) in 1072 after the Bulgarian nobility in Skopje revolted against the Byzantine Empire and proclaimed him their leader as a descendant of the Cometopuli, though his reign ended in 1073 when he was captured by the Byzantines. In 1078 he returned to Duklja, and upon the death of his father in 1081 he succeeded the throne. He strengthened ties with the Pope, acquiring an Archbishopric.
