Ashur-nadin-ahhe I (Aššur-nādin-aḫḫē I)[3] was a king of Assyria in the 15th century BC.
He took power after the death of his father, Ashur-rabi I.
During his reign, Assyria became a sporadic vassal of Mitanni.
He was overthrown by his brother Enlil-Nasir II.
[4] A letter survives from him congratulating Egyptian Pharaoh Thutmose III on his victories in Palestine and Syria.
