The lion who rules Narnia in C.S. Lewis’s Chronicles of Narnia is Aslan. He is the central moral and royal figure of the series, appearing as creator, guide, judge, and protector across several books.
Aslan’s name comes from the Turkish word for “lion.” Lewis gave the character a majestic role and associated him with sacrificial love, resurrection, and authority, while the Narnia books remain works of imaginative fiction rather than direct retellings of biblical stories.
Aslan appears in all seven Chronicles of Narnia novels, although his presence and role vary from book to book. He creates Narnia through song in The Magician’s Nephew and remains central to the final events of The Last Battle.
