Rhediw

Saint Rhediw (in Latin Redicus) is a saint of Wales from the early Church, linked with Llanllyfni in Gwynedd, in the north of the country. He is thought to have been born toward the beginning of the fifth century; the calendar places him in the sixth.

Little is known about him. He is said to have been born in Arfon and to have become an important official of the Church at Augustodunum, today Autun, in Gaul. A church in Llanllyfni is dedicated to him, and it is said that the first church on the site was founded in the fourth century. A well beside the church was once used for baptising, and on Llanllyfni Mountain stands the megalith called Eisteddfa Rhedyw. His festival day is kept at Llanllyfni on 6 July.

The Orthodox calendar commemorates him as a saint of the undivided Church on 11 November (New Calendar).
