Where is fight club banned?

"Fight Club," the novel by Chuck Palahniuk and its film adaptation directed by David Fincher, has faced bans and censorship in various places due to its themes of violence, anti-establishment sentiment, and mature content. Notably, some schools and libraries in the United States have restricted access to the book, and certain countries may also limit its distribution for cultural or moral reasons. However, there is no formal, widespread ban that applies universally; restrictions often vary by location and context.
