The Cthulhu Mythos is a mythopoeia and a shared fictional universe, originating in the works of American horror writer H. P. Lovecraft. The term was coined by August Derleth, a contemporary correspondent and protégé of Lovecraft, to identify the settings, tropes, and lore that were employed by Lovecraft and his literary successors. The name "Cthulhu" derives from the central creature in Lovecraft's seminal short story "The Call of Cthulhu", first published in the pulp magazine Weird Tales in 1928.
Howard Phillips Lovecraft was an American writer of weird, science, fantasy, and horror fiction. He is best known for his creation of the Cthulhu Mythos.

Lovecraftian horror, also called cosmic horror or eldritch horror, is a subgenre of horror fiction and weird fiction that emphasizes the horror of the unknowable and incomprehensible more than gore or other elements of shock. It is named after American author H. P. Lovecraft (1890–1937). His work emphasizes themes of cosmic dread, forbidden and dangerous knowledge, madness, non-human influences on humanity, religion and superstition, fate and inevitability, and the risks associated with scientific discoveries, which are now associated with Lovecraftian horror as a subgenre. The cosmic themes of Lovecraftian horror can also be found in other media, notably horror films, horror games, and comics.
