Fantasy literature is literature set in an imaginary universe, often but not always without any locations, events, or people from the real world. Magic, the supernatural and magical creatures are common in many of these imaginary worlds. Fantasy literature may be directed at both children and adults.

Fantasy is a subgenre of speculative fiction and is distinguished from the genres of science fiction and horror by the absence of scientific or macabre themes, respectively, though these genres overlap. Historically, most works of fantasy were written, however, since the 1960s, a growing segment of the fantasy genre has taken the form of films, television programs, graphic novels, video games, music and art.

Many fantasy novels originally written for children and adolescents also attract an adult audience. Examples include Alice's Adventures in Wonderland, the Harry Potter series, The Chronicles of Narnia, and The Hobbit.
