The Witches is a children's book by the Norwegian-origined British author Roald Dahl, first published in London in 1983 by Jonathan Cape. The book, like many of Dahl's works, is illustrated by Quentin Blake. The story is partly set in Norway and partly in the United Kingdom, focusing on the experiences of a young boy and his Norwegian grandmother. Its content has made the book the frequent target of censors. It appears on the American Library Association list of the 100 Most Frequently Challenged Books of 1990 to 1999, at number twenty-two. The book was adapted into an unabridged audio reading by Lynn Redgrave (ISBN 0-060-53616-0), a stage play and a two-part radio dramatisation for the BBC, a 1990 movie directed by Nicolas Roeg and an opera by Marcus Paus and Ole Paus.
