Mythpunk refers to “a subgenre of mythic fiction” in which classical folklore and faerie tales get hyperpoetic postmodern makeovers. Coined by author Catherynne M. Valente
, the term describes a brand of speculative fiction which starts in folklore and myth and adds elements of postmodern fantastic techniques: urban fantasy, confessional poetry, non-linear storytelling, linguistic calisthenics, worldbuilding, and academic fantasy.
