John Allen Stagliano (born November 29, 1951 in Chicago, Illinois), also known as buttman, is an American entrepreneur, pornographic actor, producer, and director. Stagliano, who was a Chippendale dancer before entering porn, is best known for his Buttman series of films, which are credited with sparking the "gonzo" adult film genre. These films involve dedicated butt worship, highlighting the female buttocks, with actors often licking, kissing and playfully biting the female behind, not necessarily anything to do with anal sex. Early Stagliano productions had little to no anal sex in them at all and were critically acclaimed for the showcasing of his buttocks fetish. Later Buttman films included numerous anal-sex scenes, often featuring Stagliano himself.

In 1997, Stagliano tested positive for HIV. To date, medication has kept the virus in check. He continues to produce adult films and still acts in non-sexual roles. He is married to former porn star Tricia Devereaux (also HIV positive). Stagliano espouses a libertarian political philosophy, and as such is a significant financial contributor to the Cato Institute and the Reason Foundation (both libertarian think tanks).

Stagliano owns the adult video production company Evil Angel. The company distributes porn from directors such as Rocco Siffredi, John Leslie, Joey Silvera and Belladonna. Ass-to-mouth shots were a hallmark of his early films with Rocco Siffredi — a standard in today's adult productions; these scenes often include multiple male actors.

Since October 2004, Stagliano has produced and directed a Las Vegas show called Fashionistas based on his porn film of the same name.
