Erewhon: or, Over the Range is a novel by English writer Samuel Butler, first published anonymously in 1872, set in a fictional country discovered and explored by the protagonist. The book is a satire on Victorian society.

Samuel Butler was an English novelist and critic, best known for the satirical utopian novel Erewhon (1872) and the semi-autobiographical novel The Way of All Flesh. Both novels have remained in print since their initial publication. In other studies he examined Christian orthodoxy, evolutionary thought, and Italian art, and made prose translations of the Iliad and Odyssey that are still consulted.
