Arshak II (Georgian: არშაკ) or Arsuk (არსუკ) (died in AD 1), of the Nimrodid Dynasty, was a king of Iberia (Kartli, eastern Georgia) from c. 20 BC to AD 1.
According to a legendary account from the medieval Georgian annals, he was a descendant of Nimrod and Parnavaz through his father, Mirian II, and was a member of the Arshakuniani dynasty through his mother. Arshak faced with the return of the exiled P'arnabazid prince Aderki (son of Kartam, adopted son of Bratman). From the battle, Aderki emerged victorious and became a king.
