(Στασίοικος), prince or dynast of Marion in Cyprus, was one of the petty princes among whom that island was divided at the period of its conquest by Ptolemy, king of Egypt. Upon that occasion Stasioecus was one of the first to join Seleucus, the admiral of the Egyptian fleet, and to place himself under the supremacy of Ptolemy : but in B. C. 313 he abandoned the alliance of that monarch, and, in common with several of the other princes of the island, entered into negotiations with Antigonus. Before, however, the latter could lend them any support, Ptolemy himself arrived in Cyprus with a fleet and army, took Stasioecus prisoner, and razed his city to the ground. (Diod. 19.62, 79.)
