"The Whisperer in Darkness" is a 26,000-word novella by H. P. Lovecraft. Written February–September 1930, it was first published in Weird Tales, August 1931. Similar to "The Colour Out of Space" (1927), it is a blend of horror and science fiction. Although it makes numerous references to the Cthulhu Mythos, the story is not a central part of the mythos, but reflects a shift in Lovecraft's writing at this time towards science fiction. The story also introduces the Mi-go, an extraterrestrial race of fungoid creatures.
