The American Library Association ranks Brave New World as No. 52 on their list of most challenged books.
The following list includes some notable incidents in which it has been censored, banned, or challenged:
- In 1932, the book was banned in Ireland for its language, and for supposedly being anti-family and anti-religion.
- In 1965, a Maryland English teacher alleged that he was fired for assigning Brave New World to students. The teacher sued for violation of First Amendment rights but lost both his case and the appeal.
- The book was banned in India in 1967, with Huxley accused of being a "pornographer".
- In 1980, it was removed from classrooms in Miller, Missouri among other challenges.
- In 1982, Polish author Antoni Smuszkiewicz, in his analysis of Polish science-fiction Zaczarowana gra ("The Magic Game"), presented accusations of plagiarism against Huxley. Smuszkiewicz showed similarities between Brave New World and two science fiction novels written earlier by Polish author Mieczysław Smolarski, namely Miasto światłości ("The City of Light", 1924) and Podróż poślubna pana Hamiltona ("Mr Hamilton's Honeymoon Trip", 1928). Smolarski wrote in his open letter to Huxley: "This work of a great author, both in the general depiction of the world as well as countless details, is so similar to two of my novels that in my opinion there is no possibility of accidental analogy."
- Kurt Vonnegut said that in writing Player Piano (1952), he "cheerfully ripped off the plot of Brave New World, whose plot had been cheerfully ripped off from Yevgeny Zamyatin's We".
