"The Slithering Shadow" is one of the original short stories starring the fictional sword and sorcery hero Conan the Cimmerian, written by American author Robert E. Howard and first published in the September 1933 issue of Weird Tales magazine. "The Slithering Shadow" is the original title, but the story is also known as "Xuthal of the Dusk" in further publications. It is set in the fictional Hyborian Age, and concerns Conan discovering a lost city in a remote desert while encountering a Lovecraftian demon known as Thog. The story was republished in the collections The Sword of Conan (Gnome Press, 1952) and Conan the Adventurer (Lancer Books, 1966). It has more recently been published in the collections The Conan Chronicles Volume 1: The People of the Black Circle (Gollancz, 2000) as "The Slithering Shadow" and in Conan of Cimmeria: Volume One (1932-1933) (Wandering Star, 2002) and The Coming of Conan the Cimmerian (Del Rey, 2003) as "Xuthal of the Dusk."
