Bhob Stewart is an American writer, editor, artist and film maker who has written for a variety of publications over a span of five decades. His articles and reviews have appeared in TV Guide, Publishers Weekly and other publications, along with online contributions to All Movie Guide, the Collecting Channel and other sites.

Stewart got his start in publishing in science fiction fandom. He published The EC Fan Bulletin, the first EC fanzine in 1953; co-edited the Hugo Award-winning science fiction fanzine Xero (1960-1963), and is credited with coining the term "underground comics" during a panel discussion at a comics convention in 1966. He teamed with EC Comics publisher Bill Gaines to choose stories for The EC Horror Library of the 1950s (1971), and later worked closely with Mad's cartoonists while editing the Mad Style Guide (1994) and Gibson's line of Mad greeting cards (1995).

The co-author of Scream Queens (Macmillan, 1978), he scripted for animation (Kissyfur); wrote and acted in underground films (The Year the Universe Lost the Pennant [1961], Hang Up [1969]); wrote comics for several publishers (Byron Preiss, Marvel, Warren, Charlton, Heavy Metal); succeeded Vaughn Bode as editor of Gothic Blimp Works, the comix supplement for the East Village Other; edited and designed magazines (Castle of Frankenstein, Flashback); devised humor products for Topps; and introduced DC Comics to the world of trading cards as editor of DC's first card series (Cosmic Cards, Cosmic Teams). His readings of fantasy stories aired on Pacifica Radio's Midnight Chimes, and he has contributed to numerous newspapers (The Real Paper), magazines (The Realist, Galaxy Science Fiction) and books (Bare Bones).

Time columnist Richard Corliss noted that "Bhob Stewart's handsome, comprehensive Against the Grain: Mad Artist Wallace Wood" (TwoMorrows, 2003) is a "gorgeous book on Wally Wood's art." (Stewart worked with Wood for a period starting in the late 1960s). In addition to the many illustrations, this biographical anthology features a selection of articles by artists once associated with Wood's studio. Stewart's biography of Wood can also be read at his blog, Potrzebie, where it is formatted with a different selection of Wood's artwork.
