Aslan is the central lion character in C.S. Lewis's Narnia series. He is the ruler of Narnia and the most important recurring figure across the seven books.
Aslan appears as a powerful, wise, and benevolent talking lion. He guides characters, opposes evil, and restores order when Narnia is threatened. In The Lion, the Witch and the Wardrobe, he sacrifices himself to save Edmund Pevensie and later returns to life, making that book's central story one of the best-known episodes in the series.
Lewis said that Aslan was not intended to be a simple allegorical code for one figure in every detail. Nevertheless, Aslan's actions and titles strongly echo Christian ideas, especially sacrifice, resurrection, judgment, and kingship. Lewis's imaginative approach allowed those themes to operate through a fantasy narrative.
The name Aslan comes from the Turkish word for “lion.” The character is voiced or portrayed in many screen adaptations, but the original Aslan is Lewis's literary creation.
