Everett Franklin Bleiler (April 30, 1920 – June 13, 2010) was an American editor, bibliographer, and scholar of science fiction, detective fiction, and fantasy literature. In the late 1940s and early 1950s, he co-edited the first "year's best" series of science fiction anthologies, and his Checklist of Fantastic Literature has been called "the foundation of modern SF bibliography". Among his other scholarly works are two Hugo Award–nominated volumes concerning early science fiction—Science-Fiction: The Early Years and Science-Fiction: The Gernsback Years—and the massive Guide to Supernatural Fiction.
