Cunobeline or Cunobelinus (also written Kynobellinus and sometimes abbreviated to Cunobelin) (late 1st century BCE - 40s CE) is a historical king in pre-Roman Britain, known from passing mentions by classical historians Suetonius and Dio Cassius, and from his many inscribed coins.
He appears to have controlled a substantial portion of southeastern England, and is called "Britannorum rex" ("king of the Britons") by Suetonius.
He also appears in British legend as Cynfelyn (Welsh), Kymbelinus (Medieval Brito-Latin) or Cymbeline (Shakespeare, et al.
), in which form he is the subject of a play by William Shakespeare.
His name is a compound made up of cuno- "hound" and "Belenos" (the god) Belenus.
