Tiberius Julius Sauromates II Philocaesar Philoromaios Eusebes, also known as Sauromates II (Greek: Τιβέριος Ἰούλιος Σαυρομάτης Β΄ Φιλοκαῖσαρ Φιλορωμαῖος Eὐσεβής, Philocaesar Philoromaios Eusebes, the epithets meaning "friend of Caesar, friend of Rome, pious one"[1]) was a Roman client king of the Bosporan Kingdom.

[8][6][9][10] Eupator died at some point between 170 and 172[2] and Sauromates II succeeded him as Bosporan King, reigning from that date until his death in 210/211.

He was a contemporary of the Roman Emperors Marcus Aurelius, Commodus, Pertinax, Didius Julianus, Septimius Severus and Caracalla.

[12] In order to improve the flagging economy of his kingdom, Sauromates II initiated a series of monetary reforms in 186 that, over the course of a decade, gradually reduced the weight of his bronze coinage while increasing the circulation of the golden stater.

[13] In the last decade of the 2nd century AD, the coins of Sauromates II also commonly featured the portrait of Septimius Severus; it is not known whether or not this was a command given by the Roman emperor to his client or if the Bosporan king did this on his own volition.
