Vardanes I was a king of the Parthian Empire from 40 to 46 AD. He was the heir apparent of his father Artabanus II (r. 12–40), but had to continually fight against his brother Gotarzes II, a rival claimant to the throne. Vardanes' short reign ended when he was assassinated while hunting at the instigation of a party of Parthian nobles .
