The Agrianes (Ancient Greek: Ἀγρίανες, Agrianes, or Agrianoi) or Agrianians, were a tribe whose country was centered at Upper Strymon, in present-day western Bulgaria, and also held areas of southeasternmost Serbia in the ancient Roman provinces of Dacia Mediterranea, at the time situated north of the Dentheletae. In the times of Philip II, the territory of the Agrianes was administered by Pella. They were crack javelin throwers and an elite unit of Alexander the Great's light infantry, who fought under the command of General Attalus.
Their name in Ancient Greek was Ἀγρίανες. The ethnonym is of Indo-European origin, from *agro- "field" (cf. Lat. ager, Gk. ἀγρός agros, Eng. acre). An early name of the Rhodopes was Achrida, which may be a cognate.
Herodotus described them as a tribe of Paeonia, together with the Odomanti and Doberes in the vicinity of Pangaeum. The only writer who describes the Agrianes as Thracians is Theopompus.

An ethnocultural region called "Graovo" remains in Pernik Province, along with a group of Pomaks with a similar name.
