Fantastic Mr Fox is a children's novel written by British author Roald Dahl. It was published in 1970, by George Allen and Unwin in the UK and Alfred A. Knopf in the U.S., with illustrations by Donald Chaffin. The first U.K. Puffin paperback, first issued in 1974, featured illustrations by Jill Bennett. Later editions have featured illustrations by Tony Ross (1988) and Quentin Blake (1996). The story is about Mr Fox and how he outwits his farmer neighbours to steal their food from right under their noses. In 2009, it was adapted into a stop-motion animated film by Wes Anderson.

Mr Fox is an anthropomorphic, tricky, and clever fox who lives underground beside a tree with his wife and four children. To feed his family, he makes nightly visits to local farms owned by three cruel, rude, wicked and dim-witted farmers named Boggis, Bunce and Bean, whereupon he seizes the livestock available on each man's farm; chickens from Boggis, ducks or geese from Bunce, and turkeys from Bean. Tired of being outsmarted by Mr Fox, the triumvirate devise a plan to ambush him as he leaves his burrow, but they succeed only in shooting off his tail.

The three farmers then dig up the Foxes' burrow using spades and then excavators. The Foxes manage to escape by burrowing further beneath the ground to safety. The farmers are ridiculed for their persistence, but they refuse to give up and vow not to return to their farms until they have caught Mr Fox. They then choose to lay siege to the fox, surrounding Mr Fox's hole and waiting until he is hungry enough to come out. Cornered by their enemies, Mr Fox and his family, and all the other underground creatures that live around the hill, begin to starve.
