"The Canterville Ghost" is a short story by Oscar Wilde. It was the first of Wilde's stories to be published, appearing in two parts in The Court and Society Review, 23 February and 2 March 1887.

The story is about an American family who move to a castle haunted by the ghost of a dead nobleman, who killed his wife and was starved to death by his wife's brothers. It has been adapted for the stage and screen several times.

The home of the Canterville Ghost was the ancient Canterville Chase, which has all the accoutrements of a traditional haunted house. Descriptions of the wainscoting, the library panelled in black oak, and the armour in the hallway characterise the setting. Wilde mixes the macabre with comedy, juxtaposing devices from traditional English ghost stories such as creaking floorboards, clanking chains, and ancient prophecies.

The story begins when the American Minister Mr Otis and his family move into Canterville Chase, despite warnings from Lord Canterville that the house is haunted. Mr Otis says that he will take the furniture as well as the ghost at valuation. The Otis family includes Mr and Mrs Otis, their eldest son Washington, their daughter Virginia, and the Otis twins. The other characters include the Canterville Ghost, the Duke of Cheshire (who wants to marry Virginia), Mrs Umney (the housekeeper), and Rev Augustus Dampier. At first, none of the Otis family believe in ghosts, but shortly after they move in, none of them can deny the presence of Sir Simon de Canterville. The family hears clanking chains, they witness reappearing bloodstains on the floor just by the fireplace, which are removed every time they appear in various forms. But, humorously, none of these scare the Otis family in the least. In fact, upon hearing the clanking noises in the hallway, Mr Otis promptly gets out of bed and pragmatically offers the ghost Tammany Rising Sun Lubricator to oil his chains.

Despite the ghost's efforts to appear in the most gruesome guises, the family refuses to be frightened, and Sir Simon feels increasingly helpless and humiliated. When Mrs Otis notices a mysterious red mark on the floor, she simply replies that " she does not at all care for blood stains in the sitting room". When Mrs Umney informs Mrs Otis that the blood stain is indeed evidence of the ghost and cannot be removed, Washington Otis, the eldest son, suggests that the stain will be removed with Pinkerton's Champion Stain Remover and Paragon Detergent: a quick fix, like the Tammany Rising Sun Lubricator, and a practical way of dealing with the problem.
