Helenos (Ancient Greek: Ἕλενος) was a Ptolemaic governor of Cyprus in the second century BC. He came from Cyrene and was the son of either a man called Apollonius or of Apollodorus the epistrategos of Thebais. It is unlikely that Helenus was dead in 106 BC. In that year, Cleopatra III and Ptolemy X had clashed and Cleopatra assumed sole rule in Alexandria. As a close associate of her son, Helenus would not have been suitable in the role of the queen's priest, so she probably had him replaced.
