Enlil-bāni,[nb 1] c. 1860–1837 BC (MC), was the 10th king of the 1st Dynasty of Isin and reigned 24 years according to the Ur-Isin kinglist.

A certain Ikūn-pî-Ištar[nb 2] is recorded as having ruled for 6 months or a year, between the reigns of Erra-imittī and Enlil-bāni according to two variant copies of a chronicle.

Uruk, too, seceded during his reign and, as his power crumbled, he may have had the Chronicle of Early Kings[i 4] redacted to provide a more legendary tale of his accession than the rather mundane act of usurpation that it may well have been.

[3] The colophon of a medical text,[i 5] “when a man's brain contains fire,”[nb 4] from the Library of Ashurbanipal reads: “Proven and tested salves and poultices, fit for use, according to the old sages from before the flood[nb 5] from Šuruppak, which Enlil-muballiṭ, sage (apkallu) of Nippur, left (to posterity) in the second year of Enlil-bāni.”[4][5][6] Enlil-bāni found it necessary to "build anew the wall of Isin which had become dilapidated,"[i 6] which he recorded on commemorative cones.

He was a prodigious builder, responsible for the construction of the é-ur-gi7-ra, “the dog house,”[i 8] temple of Ninisina, a palace,[i 9] also the é-ní-dúb-bu, “house of relaxation,” for the goddess Nintinugga, “lady who revives the dead,”[i 10] the é-dim-gal-an-na, “house - great mast of heaven,”[i 11] for the tutelary deity of Šuruppak, the goddess Sud, and finally, the é-ki-ág-gá-ni for Ninibgal, the “lady with patient mercy who loves ex-votos, who heeds prayers and entreaties, his shining mother.”[i 12][7] Two large copper statues were taken to Nippur for dedication to Ningal, which Iddin-Dagān had fashioned 117 years earlier but had been unable to deliver, “on account of this, the goddess Ninlil had the god Enlil lengthen the life span of Enlil-Bāni.”[i 13][8] He is recorded, in two foundation nails, as having built (or possibly rebuilt) a temple to the goddess Annunitum.
