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.
The Necronomicon, also referred to as the Book of the Dead, or under a purported original Arabic title of Kitab al-Azif, is a fictional grimoire appearing in stories by the horror writer H. P. Lovecraft and his followers. It was first mentioned in Lovecraft's 1924 short story "The Hound", written in 1922, though its purported author, the "Mad Arab" Abdul Alhazred, had been quoted a year earlier in Lovecraft's "The Nameless City". Among other things, the work contains an account of the Old Ones, their history, and the means for summoning them.
Nyarlathotep is a fictional character created by H. P. Lovecraft. The character is a malign deity in the Cthulhu Mythos, a shared universe. First appearing in Lovecraft's 1920 prose poem "Nyarlathotep", he was later mentioned in other works by Lovecraft and by other writers. Later writers describe him as one of the Outer Gods, an alien pantheon.
Arkham is a fictional city situated in Massachusetts. An integral part of the Lovecraft Country setting created by H. P. Lovecraft, Arkham is featured in many of his stories and those of other Cthulhu Mythos writers.
The King in Yellow is a book of short stories by the American writer Robert W. Chambers, first published by F. Tennyson Neely in 1895. The book is named for the fictional play with the same title which recurs as a motif through some of the stories. The first half of the book features highly esteemed horror stories, and the book has been described by critics such as E. F. Bleiler and T. E. D. Klein as a classic in the field of the supernatural. Lin Carter called it "an absolute masterpiece, probably the single greatest book of weird fantasy written in this country between the death of Poe and the rise of Lovecraft".
"The Call of Cthulhu" is a short story by American writer H. P. Lovecraft. Written in the summer of 1926, it was first published in the pulp magazine Weird Tales in February 1928.

At the Mountains of Madness is a science fiction-horror novella by American author H. P. Lovecraft, written in February/March 1931 and rejected that year by Weird Tales editor Farnsworth Wright on the grounds of its length. It was originally serialized in the February, March, and April 1936 issues of Astounding Stories. It has been reproduced in numerous collections.
The Dream-Quest of Unknown Kadath is a novella by American writer H. P. Lovecraft. Begun probably in the autumn of 1926, the draft was completed on January 22, 1927 and it remained unrevised and unpublished in his lifetime. It is both the longest of the stories that make up his Dream Cycle and the longest Lovecraft work to feature protagonist Randolph Carter. Along with his 1927 novel The Case of Charles Dexter Ward, it can be considered one of the significant achievements of that period of Lovecraft's writing. The Dream-Quest combines elements of horror and fantasy into an epic tale that illustrates the scope and wonder of humankind's ability to dream.
"The Nameless City" is a short horror story written by American writer H. P. Lovecraft in January 1921 and first published in the November 1921 issue of the amateur press journal The Wolverine. It is often considered the first story set in the Cthulhu Mythos world. In the story, the protagonist travels to the middle of the Arabian Desert to explore an ancient underground city.
"The Haunter of the Dark" is a horror short story by American author H. P. Lovecraft, written between 5–9 November 1935 and published in the December 1936 edition of Weird Tales. It was the last written of the author's known works, and is part of the Cthulhu Mythos. The epigraph to the story is the second stanza of Lovecraft's 1917 poem "Nemesis".
Lovecraft Country is a term coined for the New England setting used by H. P. Lovecraft in many of his weird fiction stories, which combines real and fictitious locations. This setting has been elaborated on by other writers working in the Cthulhu Mythos. The phrase was not in use during Lovecraft's own lifetime; it was coined by Keith Herber for the Lovecraftian role-playing game Call of Cthulhu.
Lovecraftian horror, sometimes used interchangeably with "cosmic 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.
"The Festival" is a short story by H. P. Lovecraft written in October 1923 and published in the January 1925 issue of Weird Tales.
"The Rats in the Walls" is a short story by American author H. P. Lovecraft. Written in August–September 1923, it was first published in Weird Tales, March 1924.
"The Horror at Red Hook" is a short story by American writer H. P. Lovecraft, written on August 1–2, 1925. "Red Hook" is a transitional tale, situated between the author's earlier work and the later Cthulhu Mythos. Although the story depicts a sinister cult, this cult offers a conventionally occult devil-worshipping threat, rather than the cosmic threat depicted in his later work. Living in poverty in the slum of Red Hook at the time of writing, Lovecraft was at this time urgently attempting to widen his markets in the pulp magazines. By having an unusually proactive Irish New York police detective as his protagonist, he hoped for a swift sale to a detective pulp, which would have opened up a new market other than his usual Weird Tales magazine. He did not get such a sale, and had to fall back on Weird Tales. "Red Hook" was thus first published in the January 1927 issue of Weird Tales.
"Through the Gates of the Silver Key" is a short story co-written by American writers H. P. Lovecraft and E. Hoffmann Price between October 1932 and April 1933. A sequel to Lovecraft's "The Silver Key", and part of a sequence of stories focusing on Randolph Carter, it was first published in the July 1934 issue of Weird Tales.
