Nominoe or Nomenoe (French: Nominoë; Breton: Nevenoe; b. c. 800, d. 7 March 851) was the first Duke of Brittany from 846 to his death. He is the Breton pater patriae and to Breton nationalists he is known as Tad ar Vro (“father of the country”).
He was the second son of Count Erispoe or Erispoë of Poher, King of the Browaroch (775–812), and younger brother of Count Riwallon or Rivallon III of Poher (?–857).
After a general rebellion which had enveloped the entire Carolingian Empire was put down, a general assembly was held at Ingelheim in May 831. It was probably there that the emperor Louis the Pious appointed Nominoe, a Breton, to rule the Bretons (which corresponded to “almost all” of Brittany).
