Artatama II was a usurper to the throne of king Tushratta of Mitanni in the fourteenth century BC. He may have been a brother of Tushratta or belonged to a rival line of the royal house. The Hittite king Suppiluliuma I made a treaty with Artatama following his invasion of Mitanni. His son, Shuttarna III, ruled Mitanni after him.
