"The Black Stone" is a horror short story by American writer Robert E. Howard, first published in the November 1931 issue of Weird Tales. The story introduces the character of Justin Geoffrey, a mad poet, and the fictitious book Unaussprechlichen Kulten by Friedrich von Junzt. The story is part of the Cthulhu Mythos, and follows the same pattern and has the same features as much of H. P. Lovecraft's classic work.
