Laudine is a character from the 12th-century Arthurian romance Yvain, or The Knight with the Lion by the French poet Chrétien de Troyes. Her name is likely a feminine derivative of Lot 2, the legendary king of Lothian, or derived from the same place name as the region. There is general consensus that the name was coined by Chrétien based on the toponym "Landuc," the enchanted territory over which she rules in the poem.
