Amis and Amiloun is a Middle English romance in tail rhyme from the late thirteenth century. The 2508-line poem tells the story of two friends, one of whom is punished by God with leprosy for engaging in a trial by ordeal after the other has been seduced and betrayed. The poem is praised for the technical competency displayed in the stanzaic organization, though its quality as a chivalric romance has been debated. It is found in four manuscripts ranging from c. 1330 to c. 1500, including the Auchinleck Manuscript.
