List of Welsh saints
This list of Welsh saints includes Christian saints with Welsh connections, either because they were of Welsh origin and ethnicity or because they travelled to Wales from their own homeland and became noted in their hagiography for their work there. The pagan Celts of Britain had already been extensively Christianized during the Roman period: although only four victims of Diocletian's persecution are now known (Saints Alban, "Amphibalus", and Julius and Aaron), Britons met the pagan Saxon invaders largely as Christians prior to being driven back to Wales, Cornwall, and Brittany.
