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.

The Lion, the Witch and the Wardrobe is a portal fantasy novel for children by C. S. Lewis, published by Geoffrey Bles in 1950. It is the first published and best known of seven novels in The Chronicles of Narnia (1950–1956). Among all the author's books, it is also the most widely held in libraries. It was the first of The Chronicles of Narnia to be written and published, but is marked as volume two in recent editions that are sequenced according the stories' internal chronology. Like the other Chronicles, it was illustrated by Pauline Baynes, and her work has been retained in many later editions.
