The fictional world in C.S. Lewis’s Narnia books is called Narnia.
Narnia is both the name of the central country and the name commonly used for the broader fictional setting of the seven-book series. Lewis depicts it as a world populated by talking animals, mythical creatures, humans, and powerful supernatural beings. The land is created in The Magician’s Nephew and reaches its conclusion in The Last Battle.
The books follow different human visitors, including the Pevensie children, Digory Kirke, Polly Plummer, and Eustace Scrubb. Time does not pass at the same rate in Narnia and our world, which allows children from twentieth-century England to appear in different periods of Narnian history.
Narnia is sometimes mistakenly treated as the name of the whole universe. Lewis’s setting also includes other regions and worlds, such as Archenland, Calormen, and the Wood between the Worlds. Still, Narnia is the central and defining location of the series.
