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"
