Pharnabazus, a Persian soldier and diplomat, is the son of Pharnaces II of Phrygia and grandson of Pharnabazus I of Phrygia, and great grandson of Artabazus.

He and his male ancestors had governed the satrapy of Phrygia on the Hellespont from its headquarters at Dascylium since 478 BCE.

His son Artabazus is a satrap of Phrygia.

According to research by Theodor Nöldeke, he was descended from Otanes, one of the associates of Darius in the murder of Smerdis.
