Vonones I (ΟΝΩΝΗΣ Onōnēs on his coins) was an Arsacid prince, who ruled as King of Kings of Parthian Empire from 8 to 12, and subsequently as king of Armenia from 12 to 18. He was the eldest son of Phraates IV (r. 37–2 BC) and was sent to Rome as a hostage in 10/9 BC in order to prevent conflict over the succession of Phraates IV's youngest son, Phraataces.
