Vonones II (died 51 AD) was a Parthian prince who ruled as king of Media Atropatene and briefly as king of the Parthian Empire.

Vonones was not from the ruling branch of the Arsacid royal family.

His father has been variously identified as being a member of the Atropatid dynasty,[2] or as a Dahae prince descended from the former Arsacid monarch Mithridates II (r. 124–88 BC).

However, he died a few months into his reign and was succeeded by his son, Vologases I. Tacitus wrote that Vonones II “knew neither success nor failure which have deserved to be remembered to him.

[5] Vonones II had 3 sons who, respectively, held the thrones of Parthia, Media Atropatene and Armenia: Pacorus,[7] Vologases I,[5] and Tiridates I.
