The Hittites were an Ancient Anatolian people who established an empire at Hattusa in north-central Anatolia around the 18th century BC. This empire reached its height during the mid-14th century BC under Suppiluliuma I, when it encompassed an area that included most of Asia Minor as well as parts of the northern Levant and Upper Mesopotamia. After c. 1180 BC, the empire came to an end during the Bronze Age collapse, splintering into several independent "Neo-Hittite" city-states, some of which survived until the 8th century BC.

The Hittite language was a member of the Anatolian branch of the Indo-European language family. They referred to their native land as Hatti, and to their language as Nesili (the language of Nesa). The conventional name "Hittites" is due to their initial identification with the Biblical Hittites in 19th century archaeology.

Despite the use of Hatti for their core territory, the Hittites should be distinguished from the Hattians, an earlier people who inhabited the same region (until the beginning of the 2nd millennium BC) and spoke a language possibly in the Northwest Caucasian languages group known as Hattic.
