Amadocus (Ancient Greek: Ἀμάδoκoς, romanized: Amadokos, also Amatokos) was an Odrysian ruler in Thrace, who ruled from 360 to c. 351 BC.
[3] Soon after the murder of Cotys I in September 360 BC, his son and successor Cersobleptes was faced with several opponents, including Amadocus II and Berisades.
The area under Amadocus II's control is generally identified as laying west of the river Hebrus and north of Maroneia.
It is likely that the fortified residence of a Thracian ruler on Kozi Gramadi Peak above the village of Starosel belonged to him.
In 354 or 353 BC, Cersobleptes and Philip planned joint action against Amadocus and the Athenians.
