Artashumara[1] (Mittani Aryan: Artasmara;[2][3] Akkadian: Artašumara[4]) was briefly king of Mitanni in the fourteenth century BC.
The name Artašumara is the Akkadian form of the Mittani Aryan name Artasmara, which is a cognate of the Vedic Sanskrit term ऋतस्मर (Ṛta-smara), meaning "he remembers Ṛta".[2][3]
He is known only from a single mention in a tablet found in Tell Brak "Artassumara the king, son of Shuttarna the king" and a mention in Amarna letter 17.[5][6] According to the later, after the death of Shuttarna II he briefly took power but was then murdered (by someone named Tuhi) and succeeded by his brother Tushratta[7][8]
