Šinuḫtu (Neo-Assyrian Akkadian: 𒌷𒅆𒉡𒄴𒌅 and 𒌷𒅆𒉡𒄴𒌓[1]) was a Luwian-speaking Syro-Hittite state which existed in the region of Tabal in southeastern Anatolia in the Iron Age.

Šinuḫtu was located on the site of what is now Aksaray in Turkey,[2][3][4] immediately to the south-east of Lake Tuz,[5] and consisted of its capital city and a small territory surrounding it.

[6] By c. 738 BC, the Tabalian region, including Šinuḫtu, had become a tributary of the Neo-Assyrian king Tiglath-pileser III (r. 745 – 727 BCE), possibly after his conquest of Arpad over the course of 743 to 740 BC caused the states of the Tabalian region to submit to him, or possibly as a result of a campaign of Tiglath-pileser III in Tabal.

[2][14][6] The Neo-Assyrian king Sargon II (r. 722 – 705 BC) reacted through cautionary action meant to deter the other Tabalian kingdoms from rebelling[5] by invading Šinuḫtu in 718 BCE and deporting Kiyakiyas, his family and warriors, and 7350 inhabitants of the kingdom's capital city to Assyria, where Kiyakiyas himself was executed by being burnt alive.

[2][14][11][9][15][4][16] Sargon II then abolished the kingdom of Šinuḫtu and handed its territory to the king Kurdis of the nearby state of Atuna.
