Gaius Julius Agrippa (Greek: Γαίος Ιούλιος Άγρίππας, about 72 – before 150) was a Cilician Prince and the first-born son of King Gaius Julius Alexander and Queen Julia Iotapa of Cetis. He had two younger siblings: a brother called Gaius Julius Alexander Berenicianus and a sister called Julia Iotapa.
Surviving inscriptions on his family reveal that his family were related to important members of Asian, non-Jewish and Jewish aristocracy. He was of Jewish, Nabataean, Edomite, Greek, Armenian, Medes and Persian origins. His paternal grandparents were King Tigranes VI of Armenia and his wife Opgalli. Through Tigranes, he was a descendant of King Archelaus of Cappadocia, King of Judea Herod the Great and his wife Mariamne. Agrippa along with his family and paternal relatives were among the last known descendants of the Herodian Dynasty. He was an apostate to Judaism. It is unlikely that Agrippa attempted to exert influence on Judean Politics. His name indicates that the family connections from the Herodian Dynasty were not wholly broken. His maternal grandparents were King Antiochus IV of Commagene and Queen Julia Iotapa.
