Mutakkil-Nusku, inscribed mmu-ta/tak-kil-dPA.KU (meaning "he whom Nusku endows with confidence") was king of Assyria briefly c. 1132 BC, during a period of political decline. He reigned sufficiently long to be the recipient of a letter or letters from the Babylonian king, presumed to be Ninurta-nādin-šumi, in which he was lambasted and derided.
