Shamshi-Adad IV, inscribed^mdšam-ši-^dIM, was the king ofAssyria, 1054/3–1050 BC, the 91st to be listed on theAssyrian Kinglist.^{[i 1][i 2]} He was a son ofTiglath-Pileser I (1114–1076 BC), the third to have taken the throne, after his brothersAsharid-apal-Ekur andAshur-bel-kala, and he usurped the kingship from the latter’s son, the short-reigningEriba-Adad II (1055–1054 BC). It is quite probable that he was fairly elderly when he seized the throne.

The Assyrian kinglist recalls that he "came up fromKarduniaš (i.e.Babylonia). He ousted Eriba-Adad, son of Aššur-bêl-kala, seized the throne and ruled for 4 years". The king ofBabylon wasAdad-apla-iddina, who had been installed more than a decade earlier by Shamshi-Adad brother, Ashur-bel-kala. The extent to which he was instrumental in the succession is uncertain but it seems that Shamshi-Adad may have earlier sought refuge in exile in the south.^[1]

TheSynchronistic Kinglist^{[i 3]} gives Ea-, presumed to beEa-mukin-zeri (c. 1008 BC), as his Babylonian contemporary,^[2] an unlikely pairing as he was likely to have been concurrent with the latter kings of the 2nd dynasty ofIsin during its dying throes. The political events of his reign are obscure and his fragmentary inscriptions are limited to commemorating renovation work carried out on theIštar temple atNineveh and thebīt nāmeru ("gate-tower") atAssur.^[3]

He would be succeeded by his son,Ashurnasirpal I.
