Tiberius Julius Theothorses, also known as Thothorses or Fophors (fl. second half of 3rd century died 309) was a prince and Roman Client King of the Bosporan Kingdom. Theothorses was the second-born son to the Bosporan King Teiranes and his mother was an unnamed woman. He was of Greekian and Roman ancestry. His elder brother was prince Sauromates IV, who co-ruled briefly with his father before his death in 276. In 278, during his father's reign, Theothorses was elevated by Teiranes to co-ruler. In 279, Teiranes died and Theothorses succeeded him as the sole ruler of the Bosporan Kingdom, reigning from 278 until his death around 308/309.
The client Kings of Bosporus minted a fascinating series of coins dated in the local era. The gold/silver/billon and copper staters showed the bust of the Roman Emperor on one side and the bust of the King of Bosporus on the other side.
