The Incredible Journey (1961), by Scottish author Sheila Burnford, is a children's book first published by Hodder & Stoughton, which tells the story of three pets as they travel 300 miles (480 km) through the Canadian wilderness searching for their beloved masters. It depicts the suffering and stress of an arduous journey, together with the unwavering loyalty and courage of the three animals. The story is set in the northwestern part of Ontario, which has many lakes, rivers, and widely dispersed small farms and towns.
It is usually considered a children's book, although Burnford has stated that she did not write it specifically for children. The book was a modest success when first published, but became widely known after 1963 when it was loosely adapted into a movie by the same name by Walt Disney. The story was again adapted loosely when Disney remade the film in 1993 as Homeward Bound: The Incredible Journey.
Burnford based the fictional story on the animals she and her husband owned while living in Canada: a Bull Terrier brought from England; a Siamese cat, whose mutual relationship with the terrier she described as "closer than any other cat-and-dog relationship I had ever seen"; and a young Labrador Retriever, who also developed a close relationship with the older dog.
