Fantasy is a genre of art that uses magic and other supernatural forms as a primary element of plot, theme, or setting. 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 comprises works by many writers, artists, filmmakers, and musicians, from ancient myths and legends to many recent works embraced by a wide audience today.

The genre of fantasy is generally distinguished from other works that may use things believed to be impossible by its internal consistency (the marvels do not alter their behavior without reason in a work) and its presentation as true in its context.
