For a place in the prefecture of Laconia, see Agriani (Laconia), Greece

The Agrianes were an ancient warrior-tribe who occupied, it seems, the territory north of the Thracian Maedi, the area corresponding to eastern Dardania and southern Moesia. Herodotus and Thucydides stated that they were a Paionian tribe, neither Illyrians nor Thracians.

The Agrianes were renowned for their skill in battle, and large numbers of them were enlisted in Alexander the Great's army, especially as javelin-men.

They were an independent tribe for most of their history, inhabiting a "free zone" between the Illyrian and Thracian (Odrysian) powers, in the southern Balkans.

Langarus is perhaps the most famous of the Agrianian kings.
