|King of Babylon|
|House||Dynasty of E|
Nabû-šuma-ukîn II, inscribed m[d]Nabû-šuma-úkîn[i 1] or mŠuma-[úkîn],[i 2] whose complete name is only known from the Kinglist A, was a usurper and briefly king of Babylon for one month and two days during 732 BC before he was swept aside by his successor, Nabû-mukin-zēri.
His reign was so fleeting he was omitted from the Ptolemaic Canon. His Assyrian contemporary was Tukultī-apil-Ešarra III who was too distracted campaigning in Syria to react to political events. He came to power as a disaffected former provincial governor leading a rebellion against Nabû-nādin-zēri, the son and successor of Nabû-Nasir.
He was deposed and replaced by the Chaldean chief, Nabû-mukin-zēri, of the Bīt-Amukani tribe, within weeks establishing a trend as later pretenders from the traditional Babylonian population were likewise to be displaced quickly by Chaldeans, Marduk-zakir-šumi II by Marduk-apla-iddina II in 703 BC and Nergal-ušezib by Mušezib-Marduk in 692 BC.
