Berenice, c.280–46 B.C., queen-consort of ancient Syria; wife of Antiochus II. She was called Berenice Syra. She was the daughter of Ptolemy II, and her marriage (252) to Antiochus II marked a temporary cessation in the wars between the Egyptian monarchs and the Seleucids. On the death of Antiochus, however, Laodice I, the king's divorced first wife, brought about the death of Berenice and her infant son before Berenice's brother, Ptolemy III, could arrive. New war resulted.
