Aliscans is a chanson de geste of the late twelfth century. It recounts the story of the fictional battle of Aliscans (Alescans), a disastrous defeat of a Christian army by a Saracen army. The name 'Aliscans' presumably refers to the Alyscamps in Arles. It belongs to the Guillaume d'Orange cycle, and in the action Guillaume's nephew Vivien is killed.
