Octamasades (Scythian: *Uxtamazatā, Ancient Greek: Ὀκταμασάδης, romanized: Oktamasades) was briefly a king of the Scythian/North-Caucasian tribe of the Sintis and a son of Hecataeus and Tirgatao.
He usurped the throne from his father[1] some time in 383 BC after his failed war against Octamasades' mother, Tirgatao.
The Greek name Oktamasadēs is the Hellenisation of the Scythian language name *Uxtamazatā, meaning "possessing greatness through his words.
[3] In the ensuing days of his accession to the throne, he was induced by his mother to make war on the Bosporan Kingdom who was at the time under the rule of the ambitious and militaristic ruler, Leucon.
Heeding to his mother's words, he attacked the Bosporan city of Labrytai which provoked Leucon into a battle.
