King Leodegrance /ˈliːoʊdɪɡræns/, sometimes Leondegrance, Leodogran, or variations thereof, is the father of Queen Guinevere in Arthurian legend.
His kingdom of Cameliard (or Carmelide) is usually identified with Cornwall but may be located in Breton Cornouaille near the town of Carhaix-Plouguer, which is the Carhaise of L'Histoire de Merlin (13th century).
Leodegrance had served Uther Pendragon, King Arthur's biological father and regnal predecessor.
Arthur meets Guinevere for the first time during this excursion, and they develop a love that eventually results in their fateful marriage.
[1] Leodegrance was portrayed by Patrick Stewart in the 1981 film Excalibur and by Daragh O'Malley in the 2011 television series Camelot.
