Fiona Kelleghan (born West Palm Beach, Florida) is an academic and critic specializing in science fiction and fantasy. Writing in The Washington Post, Pulitzer Prize-winning critic Michael Dirda called her "an expert on humor in genre fiction," and she is listed on the University of Miami's website as its official expert on "Science Fiction, Fantasy & Horror."

She has identified a secular, satiric literary movement within the science-fiction genre that she calls "Savage Humanism." Her critical anthology The Savage Humanists (Robert J. Sawyer Books, 2008) begins with a 17,000-word essay by her describing the movement and its practitioners, and collects stories by Gregory Frost, James Patrick Kelly, John Kessel, Jonathan Lethem, James Morrow, Kim Stanley Robinson, Robert J. Sawyer, Tim Sullivan, and Connie Willis, with introductions to each by Kelleghan. That essay, "A Definition of Savage Humanism, with Autobiographical Anecdotes," is reprinted as the cover story in the November 2008 edition of The New York Review of Science Fiction, and takes up most of that issue of the magazine.

Kelleghan's other books include Mike Resnick: An Annotated Bibliography and Guide to His Work (Farthest Star, 2000), and, as editor, 100 Masters of Mystery and Detective Fiction (Salem Press, 2001, 2 volumes) and Magill's Choice: Science Fiction and Fantasy Literature (Salem Press, 2002).
