Who is the lion figure in C.S. Lewis's Narnia books?

Aslan is the lion figure in C.S. Lewis's The Chronicles of Narnia.

Aslan is the central symbolic and moral presence of the Narnia books. He is presented as the great lion and creator or ruler of Narnia, and his appearances often mark moments of judgment, rescue, sacrifice, or renewal. His name is derived from the Turkish word for “lion.”

Aslan is commonly interpreted as a fictional representation of Christ, although Lewis's stories use their own fantasy setting rather than retelling the Gospel in a simple one-to-one allegory. The clearest Christian parallels appear in his death and return in The Lion, the Witch and the Wardrobe.

Aslan should not be confused with the human King Caspian, the faun Mr. Tumnus, or the marsh-wiggle Puddleglum. Those characters belong to Narnia's cast, but Aslan is the lion who stands at the center of its mythology.
