Eric (also Heirichus or Ehericus;[1] died 799) was the Duke of Friuli (dux Foroiulensis) from 789 to his death. He was the eldest son of Gerold of Anglachgau and by the marriage of his sister Hildegard the brother-in-law of Charlemagne.
^It has been suggested that his name is a mistranscription of Munichis.
