Agron (ruled c. 250 - 230 BCE) is the greatest king of the Ardiaean Kingdom.

The son of Pleuratus, Agron brings about a great revival among the Illyrians; during his reign, the Ardiaean State is not only the most powerful Illyrian state of the time, but also one of the greatest in the Balkans.

He succeeds in extending Illyrian rule over many peoples and cities in the Adriatic and Ionian regions.

He is most famed for his decisive victory over the Aetolians, who at the time are considered the strongest power in Greece.

Agron is mentioned by two Greek historians, Appian (95-165 CE) in his Foreign Wars and Polybius (203–120 BCE) in his Histories.

Around 231 BCE, Agron suddenly dies after his triumph over the Aetolians.

Pinnes, his son with his first wife Triteuta, officially succeeds his father as king in 230 BCE, but the kingdom is ruled by Agron's second wife, Queen Teuta.
