Ariobarzanes (in Greek Ἀριoβαρζάνης; ruled 363–337 BC) a Persian noble, succeeded his kinsman or father, Mithridates or alternatively succeeded another Ariobarzanes I of Cius, as ruler of the Greek city of Cius in Mysia, governing for 26 years between 363 BC and 337 BC for the Persian king. It is believed that it was he and his family which in mid-360s BC revolted from the rule of the Persian king Artaxerxes II, but ended up in defeat by 362 BC. He was succeeded as governor of Cius by Mithridates, possibly his son or possibly a kinsman such as a younger brother.
