Everett Franklin Bleiler (April 30, 1920 – June 13, 2010) was a renowned American editor, bibliographer, and scholar specializing in 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 comprehensive Guide to Supernatural Fiction.

Bleiler worked at Dover Publications from 1955, becoming executive vice-president of the company from 1967 until he left in 1977; he then worked for Charles Scribner's Sons until 1987. He edited several ghost story collections for Dover, which the genre historian Mike Ashley has described as having "detailed and exemplary introductions".

Bleiler was the recipient of the Pilgrim Award for lifetime achievement in science fiction scholarship in 1984, the World Fantasy Award for Life Achievement in 1988, the First Fandom Hall of Fame award in 1994, and the International Horror Guild Living Legend award in 2004.

In the 1970s, Bleiler wrote two works of fiction, not published until 2006: the fantasy novel Firegang: A Mythic Fantasy, set in the tree of Yggdrasil and spanning time and space, and Magistrate Mai and the Invisible Murderer, a detective story set in ancient China, reminiscent of Robert van Gulik's work.

Bleiler's son, Richard, is also a science fiction historian and collaborated with his father on several projects.
