Mythago Wood is a fantasy novel by British writer Robert Holdstock, published in the United Kingdom in 1984. Mythago Wood is set in Herefordshire, England, in and around a stand of ancient woodland, known as Ryhope Wood. The story involves the internally estranged members of the Huxley family, particularly Stephen Huxley, and his experiences with the enigmatic forest and its magical inhabitants. The conception began as a short story written for the 1979 Milford Writer's Workshop; a novella of the same name appeared in the September 1981 edition of The Magazine of Fantasy & Science Fiction.

Robert Paul Holdstock was an English novelist and author best known for his works of Celtic, Nordic, Gothic and Pictish fantasy literature, predominantly in the fantasy subgenre of mythic fiction.
