Phoebe Louise Adams Gloeckner (born December 22, 1960) is an American cartoonist, illustrator, painter, and novelist.

Because her mother was dating Robert Armstrong, a cartoonist in Robert Crumb's band Cheap Suit Serenaders, she met many San Francisco underground comics figures who had a profound influence upon her, including Crumb, Aline Kominsky, Bill Griffith, Terry Zwigoff, and Diane Noomin.

[2][8] Gloeckner worked prolifically as a medical illustrator from 1988, and her training is evident in her paintings and comics art, which are highly detailed and often prominently feature the human body.

Her first prominent work in fiction publishing, a series of illustrations for the RE/Search edition of J. G. Ballard's novel The Atrocity Exhibition, used clinical images of internal anatomy, sex, and physical trauma in ambiguous and evocative combinations.

Her early comics work, in the form of short stories published in a variety of underground anthologies including Wimmen's Comix, Weirdo, Young Lust, and Twisted Sisters, and in the tabloid zine, RE/Search (numbered volumes), was sporadic and rarely seen until the 1998 release of the collection A Child's Life and Other Stories.

Her novel and many of her short stories are semi-autobiographical, a frequent cause of comment due to their depiction of sex, drug use, and childhood traumas; however, Gloeckner has stated that she regards them as fiction.

Sexual content led to A Child's Life and Other Stories being banned from the public library in Stockton, California, after it was checked out by an 11-year-old reader.

[11] The film stars Alexander Skarsgård as Monroe, Kristen Wiig as Charlotte, and Bel Powley as the main character, Minnie Goetze.
