Cthulhu is a fictional character that first appeared in the short story "The Call of Cthulhu", published in the pulp magazine Weird Tales in 1928. The character was created by writer H. P. Lovecraft.
HP Lovecraft's initial short story, The Call of Cthulhu established the character as a malevolent entity trapped in an underwater city in the South Pacific called R'lyeh. The character is a central figure in Lovecraft literature, with the short story The Dunwich Horror (1928) mentioning Cthulhu, while The Whisperer in Darkness (1930) hints at the character's origins ("I learned whence Cthulhu first came, and why half the great temporary stars of history had flared forth."). The 1931 novella At the Mountains of Madness refers to the "star-spawn of Cthulhu", who warred with another race called the Old Ones before the dawn of man

It is often shortened to, "Cthulhu fhtagn," which loosely translates to, "Cthulhu waits," or "Cthulhu dreams."
