Artashumara[1] (Mittani Aryan: Artasmara;[2][3] Akkadian: Artašumara[4]) was a Hurrian ruler who briefly succeeded his father Shuttarna II as the king of Mitanni in the fourteenth century BC.
He was later assassinated by a pro-hittite group led by Tuhi who declared himself as a regent after placing Tushratta on the throne.
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.
[6][7] According to the letter, after the death of Shuttarna II, he briefly took power but was later assassinated.
