ðo]) is a short story by American writer Edgar Allan Poe, first published in the November 1846 issue of Godey's Lady's Book. The story, set in an unnamed Italian city at carnival time in an unspecified year, is about a man taking fatal revenge on a friend who, he believes, has insulted him.

Like several of Poe's stories, and in keeping with the 19th-century fascination with the subject, the narrative revolves around a person being buried alive – in this case, by immurement. As in "The Black Cat" and "The Tell-Tale Heart", Poe conveys the story from the murderer's perspective.
