Philip the Tetrarch (c. 26 BCE – 34 CE), sometimes called Herod Philip II by modern writers (see "Naming convention") was the son of Herod the Great and his fifth wife, Cleopatra of Jerusalem. As a Tetrarch, he ruled over the northeast part of his father's kingdom between 4 BCE and 34 CE after Herod's death. He was a half-brother of Herod Antipas and Herod Archelaus. He is not the same person as Herod II, whom some writers call Herod Philip I.
