Cthulhu is a fictional cosmic entity created by writer H. P. Lovecraft and first introduced in the short story "The Call of Cthulhu", published in the American pulp magazine Weird Tales in 1928. Considered a Great Old One within the pantheon of Lovecraftian cosmic entities, the creature has since been featured in numerous popular culture references. Lovecraft depicts it as a gigantic entity worshipped by cultists, in shape like an octopus, a dragon, and a caricature of human form. Its name was given to the Lovecraft-inspired universe where it and its fellow entities existed, the Cthulhu Mythos.
