The fictional land where C.S. Lewis set The Chronicles of Narnia is called Narnia.
Narnia is the principal setting of Lewis’s seven-book children’s fantasy series, published between 1950 and 1956. Human children from Earth enter this world through magical routes such as a wardrobe, a painting, a stable, and a magical ring. Narnia contains talking animals, mythical creatures, kings and queens, and a distinct history spanning many generations.
Aslan, the great lion, is Narnia’s central ruler and spiritual figure. Other regions appear in the wider setting, including Archenland, Calormen, and the Lone Islands. These places are related to Narnia but are not alternative names for it.
Readers sometimes confuse Narnia with Middle-earth, J.R.R. Tolkien’s setting, because Lewis and Tolkien were friends and members of the Oxford literary group known as the Inklings. Narnia belongs specifically to Lewis’s fiction.
