Mirian II (Georgian: მირიანი) or Mirvan (მირვანი) (c. 90–20 BC) was a king of Iberia (Kartli, eastern Georgia) from 30 to 20 BC. His reign marked the reinstatement of the Nimrodid Dynasty, a continuation of the P'arnabazids.
Mirian is known solely from the early medieval Georgian chronicles according to which he was the son of king P'arnajom murdered by his son-in-law, the Armenian Artaxiad prince Arshak who usurped the crown of Iberia. Mirian was carried to Iran, there to be brought up at the court. He returned with an Iranian army, killed Arshak's reigning grandson Bartom in battle and became king. He was succeeded by his son, Arshak II.
