"In the Penal Colony" is a short story by Franz Kafka written in German in October 1914, revised in November 1918, and first published in October 1919. As in some of Kafka's other writings, the narrator in this story seems detached from, or perhaps numbed by, events that one would normally expect to be registered with horror. Internal clues and the setting on an island suggest Octave Mirbeau's The Torture Garden as an influence. The story is set in an unnamed penal colony and describes the last use of an elaborate torture and execution device that carves the sentence of the condemned prisoner on his skin as he slowly dies over the course of twelve hours. As the plot unfolds, the reader learns more and more about the machine, including its origin and original justification.

Franz Kafka was a German-speaking Bohemian Jewish novelist and writer from Prague. He is widely regarded as one of the major figures of 20th-century literature. His work fuses elements of realism and the fantastic. It typically features isolated protagonists facing bizarre or surrealistic predicaments and incomprehensible socio-bureaucratic powers. It has been interpreted as exploring themes of alienation, existential anxiety, guilt, and absurdity. His best known works include the novella The Metamorphosis and novels The Trial and The Castle. The term Kafkaesque has entered English to describe absurd situations like those depicted in his writing.
