The Picture of Dorian Gray is a Gothic and philosophical novel by Oscar Wilde, first published complete in the July 1890 issue of Lippincott's Monthly Magazine.

Dorian Gray is the subject of a full-length portrait in oil by Basil Hallward, an artist impressed and infatuated by Dorian's beauty; he believes that Dorian's beauty is responsible for the new mood in his art as a painter.

Through Basil, Dorian meets Lord Henry Wotton, and he soon is enthralled by the aristocrat's hedonistic world view: that beauty and sensual fulfilment are the only things worth pursuing in life. Newly understanding that his beauty will fade, Dorian expresses the desire to sell his soul, to ensure that the picture, rather than he, will age and fade.

The wish is granted, and Dorian pursues a libertine life of varied amoral experiences while staying young and beautiful; all the while, his portrait ages and records every sin. Fearing the story was indecent, prior to publication the magazine's editor deleted roughly five hundred words without Wilde's knowledge.

The longer and revised version of The Picture of Dorian Gray published in book form in 1891 featured an aphoristic preface-a defence of the artist's rights and of art for art's sake-based in part on his press defences of the novel the previous year.

The content, style, and presentation of the preface made it famous in its own right, as a literary and artistic manifesto.
