Lady Chatterley's Lover is a novel by D. H. Lawrence, first published privately in 1928 in Italy, and in 1929 in France and Australia. 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. Penguin won the case, and quickly sold 3 million copies.

The story concerns a young married woman, the former Constance Reid (Lady Chatterley), whose upper class husband, Sir Clifford Chatterley, described as a handsome, well-built man, has been paralysed from the waist down due to a Great War injury. In addition to Clifford's physical limitations, his emotional neglect of Constance forces distance between the couple. Her sexual frustration leads her into an affair with the gamekeeper, Oliver Mellors, the novel's title character. The class difference between the couple highlights a major motif of the novel which is the unfair dominance of intellectuals over the working class. The novel is about Constance's realization that she cannot live with the mind alone; she must also be alive physically. This realization stems from a heightened sexual experience Constance has only felt with Mellors, suggesting that love can only happen with the element of the body, not the mind.
