The Chronicles of Narnia is a series of seven portal fantasy novels by British author C. S. Lewis. Illustrated by Pauline Baynes and originally published between 1950 and 1956, the series is set in the fictional realm of Narnia, a fantasy world of magic, mythical beasts and talking animals. It narrates the adventures of various children who play central roles in the unfolding history of the Narnian world. Except in The Horse and His Boy, the protagonists are all children from the real world who are magically transported to Narnia, where they are sometimes called upon by the lion Aslan to protect Narnia from evil. The books span the entire history of Narnia, from its creation in The Magician's Nephew to its eventual destruction in The Last Battle.

Fantasy is a genre of speculative fiction involving magical elements, typically set in a fantasy world and usually inspired by mythology or folklore. The term "fantasy" can also be used to describe a "work of this genre", usually literary.
