Caffo was a sixth-century Christian in Anglesey, north Wales, who is venerated as a saint and martyr. Little is known for certain about Caffo; his dates of birth and death are not given in the sources. He is said to have been one of the sons of St Caw, a king in northern Britain who lost his lands and sought safety with his family in Anglesey. Caffo was a companion of St Cybi, and is mentioned as carrying a red-hot coal in his clothes to Cybi without his clothes getting burnt. After leaving Cybi, Caffo was killed by shepherds in the south of Anglesey, possibly acting in retaliation for insults Caffo's brother had paid to the local ruler. The area of Caffo's death became known at some point as Llangaffo, and a church was established there: the Welsh word "llan" originally meant "enclosure" and then "church", and "-gaffo" is a modified form of the saint's name.
