"The Shambler from the Stars" is a horror short story by American writer Robert Bloch, first published in the September 1935 issue of Weird Tales. It was later included as part of his first published book, The Opener of the Way (1945), and his 1994 collection The Early Fears. A Cthulhu Mythos tale, it introduced the forbidden tome De Vermis Mysteriis (Mysteries of the Worm). Later on in 1935, Lovecraft wrote the short story "The Haunter of the Dark" as a sequel and dedicated it to Bloch. Eventually, in 1950, Bloch wrote his own sequel "".
