The Cthulhu Mythos is a shared fictional universe, based on the work of American horror writer , dealing with the cosmic horrors, the "Great Old Ones", that exist in this universe.

An ongoing theme in Lovecraft's work is the complete irrelevance of mankind in the face of these cosmic horrors—a loose pantheon of ancient, powerful deities from space who once ruled the Earth and who have since fallen into a death-like sleep.

Many different creations have been set within the mythos, both explicitly and implicitly (many works may just feature a few side references).
