Pope Caius, also called Gaius, was the bishop of Rome from 17 December 283 to his death in 296.

In all versions of the story, shortly after his recovery he went to Diocletian to warn him about his sins, and as a result was clubbed to death. He is venerated in the Catholic Church and the Orthodox Church.
