Mithridates I Callinicus (Greek, Modern (1453-);: Μιθριδάτης ὀ Кαλλίνικος) was a king of Orontid Armenian[1] descent who lived during the late 2nd century BC and early 1st century BC. Mithridates was a prince, the son, and successor of King of Commagene, Sames II Theosebes Dikaios. Before his succession in 109 BC, he married the Syrian Greek Princess Laodice VII Thea, daughter of King Antiochus VIII Grypus and Ptolemaic princess Tryphaena, as a part of a peace alliance. Mithridates embraced Greek culture. Laodice bore Mithridates a son, Antiochus I Theos of Commagene (c. 86 BC–38 BC), a prince and future king of Commagene. Mithridates died in 70 BC and Antiochus succeeded him.
