Fantasy art is a genre of art that depicts magical or other supernatural themes, ideas, creatures or settings. While there is some overlap with science fiction, horror and other speculative fiction art, there are unique elements not generally found in other forms of speculative fiction art. Depictions of ancient myths and legends, as well as depictions of modern day fantasy in the form of divine interventions and other magical or supernatural forces, are very common elements, and help distinguish fantasy art from other forms. Dragons, wizards, fairies and other fantastical and mythical creatures are common features in fantasy art.

Fantasy art is strongly linked to fantasy fiction. Indeed fantasy art pieces are often intended to represent specific characters or scenes from works of fantasy literature. Such works created by amateur artists may be called fanart.

There is a large subculture based around the creation of amateur fantasy art. This is largely centred around websites such as Elfwood. Such sites are noticeably less male-dominated than some other pursuits related to the fantasy genre.

Fantasy art should not be confused with the fantastic art genre, which can contain fantastical elements that are not always considered "fantasy" per se.

A fantasy world is a type of imaginary world, part of a fictional universe used in fantasy novels and games. Typical worlds involve magic or magical abilitiesBrian Attebery, The Fantasy Tradition in American Literature, p 166-7, ISBN 0-253-35665-2 and often, but not always, either a medieval or futuristic theme. Some worlds may be a parallel world tenuously connected to Earth via magical portals or items; a fictional Earth set in the remote past or future; or an entirely independent world set in another universe.John Grant and John Clute, The Encyclopedia of Fantasy, "Imaginary lands", p 495-5 ISBN 0-312-19869-8

Many fantasy worlds draw heavily on real world history, geography and sociology, and also on folklore.
