Gingalain (French: Guinglain) is a knight from the Arthurian legend of the Round Table. He is the title character in Le Bel Inconnu, a poem written by Renaut de Beaujeu (1180s–1230). He is also in the (destroyed) 12th-century manuscript, Gliglois. It is uncertain if the Gliglois of the medieval manuscript refers to Gawain's son or some other character in the "Fair Unknown" cycle.
