Aslan is the central Christ-like figure in C.S. Lewis’s Chronicles of Narnia. He is a great talking lion and the creator, ruler, and spiritual authority of Narnia.
Aslan appears in all seven Narnia books, although his role and the amount of page time vary from story to story. His name comes from the Turkish word for “lion,” and Lewis uses the character’s presence to represent authority, sacrifice, resurrection, judgment, and restoration without making Aslan a simple allegorical substitute in every scene.
The clearest parallel occurs in The Lion, the Witch and the Wardrobe. Aslan offers himself in place of Edmund Pevensie under the Deep Magic, is killed on the Stone Table, and returns to life through a deeper magic. The episode deliberately echoes Christian themes of sacrificial death and resurrection.
Aslan is often confused with the individual companions and heroes of the series, such as Reepicheep or Mr. Tumnus. Those characters are important Narnian figures, but neither creates Narnia nor occupies its overarching spiritual and royal role.
