Fantasy is a genre of art, literature, film, television, and music that uses magic and other supernatural forms as a primary element of either plot, theme, setting, or all three. The genre is generally distinguished from science fiction and horror by overall look, feel, and theme of the individual work, though there is a great deal of overlap between the three (collectively known as speculative fiction). In its broadest sense, fantasy covers works by many writers, artists, and musicians, from ancient myths and legends, to many recent works embraced by a wide audience today.

As with other forms of speculative fiction, actions and events in fantasy very often differ from those possible in consensus reality. In many cases, especially in older works of fantasy but in many modern works as well, this is explained by means of divine intervention, magic, or other supernatural forces. In other cases, most frequently in works of modern fantasy in the high fantasy subgenre, the story might take place in a fantasy world that is wholly different from our own, complete with distinct laws of nature that permit magic.
