Claudius Xenophon (or Xenephon) was a governor of Britannia Inferior, a province of Roman Britain around AD 223. He is named on two milestones with nearly identical texts, which can be dated to that year.[1] He succeeded Marius Valerianus, whose rule is attested in AD 222; and his governorship must have ended by AD 225, when another governor is mentioned in a fragmentary inscription, which only provides part of the name (Maximus). He is also mentioned in inscriptions in Vindolanda[2] and perhaps at Chesters.[3][4] His father is thought to be a T. Cl(audius) T. f(ilius) Papiria Xenophon, who is mentioned in inscriptions and papyri in various procuratorships in Egypt and Dacia under Commodus.[5]
