Urban fantasy is a subgenre of fantasy in which the narrative has an urban setting.
 Works of urban fantasy are set primarily in the real world and contain aspects of fantasy, such as the arrival of alien races, the discovery of earthbound mythological creatures, coexistence or conflict between humans and paranormal beings, and other changes to city life.
 A contemporary setting is not strictly necessary for a work of urban fantasy: works of the genre may also take place in futuristic and historical settings, real or imagined.
