The Horse and His Boy is a novel for children by
C. S. Lewis, published by Geoffrey Bles in
1954. It was the fifth published of seven novels in
The Chronicles of Narnia (1950–1956) and one of four that Lewis finished writing before the first book was out. It is volume three in recent editions, which are sequenced according to Narnia history. Like the others it was illustrated by
Pauline Baynes and her work has been retained in many later editions.
