Lady Chatterley's Lover is the last novel by English author D. H. Lawrence, which was first published privately in 1928, in Italy, and in 1929, in France. An unexpurgated edition was not published openly in the United Kingdom until 1960, when it was the subject of a watershed obscenity trial against the publisher Penguin Books, which won the case and quickly sold three million copies. The book was also banned for obscenity in the United States, Canada, Australia, India and Japan. The book soon became notorious for its story of the physical relationship between a working-class man and an upper-class woman, its explicit descriptions of sex and its use of then-unprintable profane words. It entered the public domain in the United States in 2024.

David Herbert Lawrence was an English novelist, short story writer, poet, playwright, literary critic, travel writer, essayist, and painter. His modernist works reflect on modernity, social alienation and industrialization, while championing sexuality, vitality and instinct. Several of his novels, Sons and Lovers, The Rainbow, Women in Love, and Lady Chatterley's Lover, were the subject of censorship trials for their radical portrayals of sexuality and use of explicit language.
