Antiochus II Theos (Ancient Greek: Ἀντίοχος ὁ Θεός, Antíochos ho Theós, meaning "Antiochus the God"; 286 – July 246 BC) was a Greek king of the Hellenistic Seleucid Empire who reigned from 261 to 246 BC. He succeeded his father Antiochus I Soter in the winter of 262–61 BC. He was the younger son of Antiochus I and princess Stratonice, the daughter of Demetrius Poliorcetes.
Antiochus II was a forceful personality who in his lifetime largely succeeded to hold the sprawling Seleucid realm intact. However his fateful decision to repudiate his first wife Laodice and marry a Ptolemaic princess Berenice as part of a peace treaty led to a succession struggle after his death that would shake the empire's foundations and cause large territorial losses.
