The Shadow over Innsmouth is a horror novella by H. P. Lovecraft. It forms part of the Cthulhu Mythos, using its motif of a malign undersea civilization. It references several shared elements of the Mythos, including place-names, mythical creatures and invocations.

Inspired by H. P. Lovecraft's classic, today's masters of horror take up their pens and turn once more to that decayed, forsaken New England fishing village with its sparkling treasure, loathsome denizens, and unspeakable evil.
