The Black Cat" is a short story by the American writer Edgar Allan Poe. It was first published in the August 19, 1843, edition of The Saturday Evening Post. In the story, an unnamed narrator has a strong affection for pets until he perversely turns to abusing them. His favorite, a pet black cat, bites him one night and the narrator punishes it by cutting its eye out and then hanging it from a tree. The home burns down but one remaining wall shows a burned outline of a cat hanging from a noose. He soon finds another black cat, similar to the first except for a white mark on its chest, but he develops a hatred for it as well. He attempts to kill the cat with an axe but his wife stops him; instead, the narrator murders his wife. He conceals the body behind a brick wall in his basement. The police soon come and, after the narrator's tapping on the wall is met with a shrieking sound, they find not only the wife's corpse but also the black cat that had been accidentally walled in with the body and alerted them with its cry.

The story is a study of the psychology of guilt, often paired in analysis with Poe's "The Tell-Tale Heart". In both, a murderer carefully conceals his crime and believes himself unassailable, but eventually breaks down and reveals himself, impelled by a nagging reminder of his guilt. "The Black Cat", which also features questions of sanity versus insanity, is Poe's strongest warning against the dangers of alcoholism.
