Arsaces is the eponymous Greek form of the dynastic name (rather than the personal names of the kings) adopted by all epigraphically attested rulers of the 'phil-hellenenic' Arsacid dynasties. The indigenous Parthian and Armenian form was Arshak.
Kings of this name include:
Arsaces I of Parthia, c. 247–211 BC
Arsaces II of Parthia, c. 211–191 BC, in older sequences known as 'Artabanus I'
Arsaces of Pontus, Roman Client King of Pontus in the second half of the 1st century BC, son of Pharnaces II of Pontus
Arsaces I of Armenia, son of Artabanus III of Parthia, King of Armenia in 35
Arsaces II (Arshak II), King of Armenia c.350–368
Arsaces III (Arshak III), King of Armenia 378–387
