Mythic fiction is literature that is rooted in, inspired by, or that in some way draws from the tropes, themes, and symbolism of myth, legend, folklore, and fairy tales. The term is widely credited to Charles de Lint and Terri Windling. Mythic fiction overlaps with urban fantasy and the terms are sometimes used interchangeably, but mythic fiction also includes contemporary works in non-urban settings. Mythic fiction refers to works of contemporary literature that often cross the divide between literary and fantasy fiction.

Windling promoted mythic fiction as the co-editor (with Ellen Datlow) of The Year's Best Fantasy and Horror annual volumes for sixteen years, and as the editor of the Endicott Studio Journal of Mythic Arts.

Though mythic fiction can be loosely based on mythology, it frequently uses familiar mythological personages archetypes (such as tricksters, or the thunderer). This is in contrast to mythopoeia, such as the works of J. R. R. Tolkien, which invent their own legends and folklore or construct entirely new pantheons.
