The fictional lion in C.S. Lewis’s Narnia series is Aslan.
Aslan is the great lion who appears throughout The Chronicles of Narnia. He is the creator and rightful ruler of Narnia, and his presence connects the separate stories across the series. Lewis portrays him as powerful, wise, compassionate, and sometimes fearsome rather than merely gentle or tame.
Aslan’s role is especially prominent in The Lion, the Witch and the Wardrobe, where he sacrifices himself to save Edmund Pevensie and is restored to life. The episode has clear Christian symbolism, although Aslan remains a character within the fictional world of Narnia.
The name is not a modern English word invented for the novels. “Aslan” is the Turkish word for “lion.” This detail is often noted by readers because Lewis had a strong interest in language, mythology, and literary symbolism.
