Hayasa-Azzi or Azzi-Hayasa (, ) was a Late Bronze Age confederation in the Armenian Highlands and/or Pontic region of Asia Minor. The Hayasa-Azzi confederation was in conflict with the Hittite Empire in the 14th century BCE, leading up to the collapse of Hatti around 1190 BCE. It has long been thought that Hayasa-Azzi may have played a significant role in the ethnogenesis of Armenians.

Assuwa () was a region of Bronze Age Anatolia located west of the Kızılırmak River. It was mentioned in Aegean, Anatolian and Egyptian inscriptions but is best known from Hittite records describing a league of 22 towns or states that rebelled against Hittite authority. It disappears from history during the fifteenth century BC.
