|Rival Parthian king|
|Reign||55 – 58|
Vardanes II was the son of Vologases I and briefly ruler of parts of the Parthian Empire. In ancient records he only appears in Tacitus. Otherwise he is only known from coins that are dated between 55 to 58 CE. He rebelled against his father from about 55 to 58 CE and must have occupied Ecbatana, since he issued coins from the mint there, bearing the likeness of a young beardless king wearing a diadem with five pendants. Nothing more about him is known.
