Sir Gingalain (Guinglain, Gingalin, Gliglois, Wigalois, etc.), also known as Le Bel Inconnu, or The Fair Unknown, is a character from Arthurian legend whose exploits are recorded in numerous versions of a popular medieval romance. His nickname differs depending on the version and language; he is known in English as Libeaus Desconus. He is the title character in Le Bel Inconnu, a poem composed by Renaut de Beaujeu sometime between the mid-1180s and 1230, and in the (destroyed) thirteenth-century manuscript, Gliglois. It is uncertain, however, if the Gliglois of the medieval manuscript refers to Gawain's son or some other character in the "Fair Unknown" cycle.
