One of the nations in the Hunnish tribal confederacy. The Akatziroi were ruled by a king called Karadach or Karidachus, and appear in the account of Priscus.

Some scholars have speculated that the Akatziroi were in fact early Khazars, hypothesizing that their name derives from the Turkic "Ak-Khazar", or "White Khazar", the name of the group of tribes composing the warrior aristocracy of the Khazar nation. Alternatively, some have suggested that the name refers to the Tharco-Dacian tribe of the Agathyrsi.
