Gabrielle Bell (born March 24, 1976, in London, England) is a British-American alternative cartoonist known for her surrealist, melancholy semi-autobiographical stories.

As described in The Comics Journal, Bell's "comics persona is that of a barely competent human being ... who stumbles through life, getting into all sorts of awkward and amusing situations.... Even in her own comics, Bell is uncomfortable with being the star, just one of the many contradictions that make her work so interesting."

In addition to her signature comics series Lucky and July Diary, and numerous collections, Bell has been widely anthologized. She was a regular contributor to Fantagraphics' quarterly anthology Mome. She has also contributed to publications such as The New Yorker, McSweeney's, Bookforum, The Believer, Vice, Kramers Ergot (Buenaventura Press), Stereoscomic (Stereoscomic), Bogus Dead (Alternative), Orchid (Sparkplug Comics), The Comics Journal Special Edition 2005 (Fantagraphics), Scheherazade (Soft Skull Press), Linus, and Shout! magazine. Her work has been included in An Anthology of Graphic Fiction, Cartoons, and True Stories (Yale University Press) and four times in the annual The Best American Comics anthology series.

Bell is the recipient of two Ignatz Awards for her work, and has been nominated for numerous other comics industry awards.

When Bell was two, her American mother divorced her British father and took Gabrielle and her brother back to the United States. Ending up in a relatively isolated rural town in Mendocino County, Bell writes that she "grew up . . . spending a lot of time reading, walking in the woods, and making up stories." As a teenager, Bell attended a college program for low-income and at-risk students hosted by Humboldt State University, where she took classes in Shakespeare and composition. When Bell was 17 she traveled in Europe, including England, where she met her British relatives. Later moving to San Francisco, Bell took art classes at the City College of San Francisco, worked in a series of retail jobs, and began self-publishing her comics.

From about 1998 to 2002, Bell annually self-published a 32-page minicomic, each of whose titles began with "Book of...", including Book of Insomnia, Book of Sleep, Book of Black, Book of Lies, and Book of Ordinary Things. Many of the stories from those comics were collected in When I'm Old and Other Stories, published by Alternative Comics in 2003.

In 2003, Bell began the self-published semi-autobiographical Lucky series. In a frank and good-humored manner, Lucky details Bell's day-to-day existence — the anguish of nude modeling; sex-obsessed, adolescent art students; and Bell's own foibles, as her avatar navigates a world of dilapidated rental apartments, low-paying jobs, yoga classes, roommate misadventures, and artistic frustration. These snippets of daily life in the Williamsburg section of Brooklyn, New York, are comforting in their familiarity; by settling into the rhythm of the artist's daily life, the reader experiences the heft of small victories and simple pleasures. The third issue of Lucky won a 2003 Ignatz Award for Outstanding Minicomic.

Lucky was collected by Drawn & Quarterly in fall 2006, and then in 2007 was relaunched as a new series (vol. 2), also by Drawn & Quarterly, which lasted two issues.
