Ninurta-tukulti-Ashur (Ninurta-tukultī-Aššur) was briefly King of Assyria in 1133 BC. He succeeded his father, the long-reigning Ashur-dan I, but the throne was very quickly usurped by his brother, Mutakkil-Nusku. Ninurta-tukulti-Ashur was forced to go into exile in Babylonia, with which he had maintained friendly relations.
