Ray Russell (4 September 1924 – 15 March 1999) was an American writer of short stories, novels, and screenplays. In 1991 he received the World Fantasy Award for Lifetime Achievement.
His most famous short fiction is "Sardonicus", which appeared in the January 1961 issue of Playboy magazine, and was subsequently adapted by Russell into a screenplay for William Castle's film version, titled Mr. Sardonicus. American writer Stephen King called "Sardonicus" "perhaps the finest example of the modern gothic ever written". "Sardonicus" was part of a trio of stories with "Sanguinarius" and "Sagittarius".
