Mark Dery is an American writer, lecturer and cultural critic. An early observer and critic of online culture, he helped to popularize the term "culture jamming" and is generally credited with having coined the term "Afrofuturism" in his essay "Black to the Future" in the anthology Flame Wars: The Discourse of Cyberculture. He writes about media and visual culture, especially fringe elements of culture for a wide variety of publications, from Rolling Stone to BoingBoing.

Culture jamming is a form of protest used by many anti-consumerist social movements to disrupt or subvert media culture and its mainstream cultural institutions, including corporate advertising. It attempts to "expose the methods of domination" of mass society.
