Midsummer Scream is a Halloween and horror film fan convention held annually in Long Beach, California at the Long Beach Convention and Entertainment Center. Widely considered to be the world's largest convention dedicated to the holiday and the horror genre, it is associated with the haunted attractions of Southern California.
