Namatius (died 558/60) was the rector of Provence under the Merovingians and later bishop of Vienne from c. 552 until his death in office.[1] He is probably identical to the person with the same name recorded among the attendants at the Council of Orange in 529.[1]
Namatius' wife, Euphrasia, became a nun after his death. She was noted for her generosity to the poor.[2]
