Aslan, the "Greatest Lion," is the central character in The Chronicles of Narnia, a series of seven fantasy novels for children written by C. S. Lewis. He is the lion of The Lion, the Witch, and the Wardrobe, and his role in Narnia is developed throughout the remaining books.

The Aslan are an extraterrestrial "Major Race" (eg., a race of intelligent beings) from the Traveller roleplaying game universe. They are four-limbed, upright, bipedal carnivore-pouncer lifeforms. They originally evolved as solitary creatures in trees and have a vague resemblance to the lion.

Aslan was a role-playing game fanzine published in Brighton and later York, UK in the late 1980s that ran to 13 issues. The title refers to both a character in The Chronicles of Narnia and an alien race in the Traveller (role-playing game). The fanzine grew out of a long-running fantasy role-playing game which took place at the University of Sussex, UK.
