Yvain, the Knight of the Lion (French: Yvain ou le Chevalier au Lion) is an Old French romance, composed by Chrétien de Troyes in the late twelfth century. Widely considered the greatest of his Arthurian romances, it is the only one based on a historical figure, Owain mab Urien, son of the ruler of the sixth century Welsh kingdom of Rheged. How much de Troyes drew from earlier Celtic traditions is a matter of some controversy.
De Troyes' tale begins with Owain's struggle to avenge his brother Calogrenant, against the mysterious knight, Esclados the Red. After defeating Esclados, he marries his widow Laudine, but is persuaded to return to adventuring by Gawain. Laudine extracts a promise that he will return in a year. Owain is unable to keep this pledge, and his efforts to win back Laudine, with the help of her maid Lunette, drive the latter part of the narrative.
Yvain has been interpreted as an attempt to reconcile the virtues of love and chivalry. Its early popularity is attested by the existence of several medieval adaptations into other languages.
