The states called Neo-Hittite, Syro-Hittite, or Luwian-Aramean were Luwian and Aramean regional polities of the Iron Age, situated in southeastern parts of modern Turkey and northwestern parts of modern Syria, known in ancient times as lands of Hatti and Aram. They arose following the collapse of the Hittite New Kingdom in the 12th century BCE, and lasted until they were subdued by the Assyrian Empire in the 8th century BCE. They are grouped together by scholars, on the basis of several cultural criteria, that are recognized as similar and mutually shared between both societies, northern (Luwian) and southern (Aramaean). Cultural exchange between those societies is seen as a specific regional phenomenon, particularly in light of significant linguistic distinctions between the two main regional languages, with Luwian belonging to the Anatolian group of Indo-European languages and Aramaic belonging to the Northwest Semitic group of Semitic languages. Several questions related to the regional grouping of Luwian and Aramaean states are viewed differently among scholars, including some views that are critical towards such grouping in general.

The Luwians were an ancient people in Anatolia who spoke the Luwian language. During the Bronze Age, Luwians formed part of the population of the Hittite Empire and adjoining states such as Kizzuwatna. During the Hittite New Kingdom, Luwian replaced Hittite as the empire's dominant language. In the early Iron Age, a number of Luwian-speaking Neo-Hittite states arose in northern Syria. The Luwians are known largely from their language, and it is unclear to what extent they formed a unified cultural or political group.
