Turya or Turanian is the ethnonym of a group mentioned in the Avesta, i.e., the collection of sacred texts of Zoroastrianism. In those texts, the Turyas closely interact with the Aryas, i.e. the early Iranians. Their identity is unknown but they are assumed to have been Iranic horse nomads from the Eurasian steppe.

Arya was the ethnonym used by Iranians during the early History of Iran. In contrast to cognates of Arya used by the Vedic people and Iranic steppe nomads, the term is commonly translated using the modern ethnonym Iranian.
