The Prisoner of Chillon (French: Le Prisonnier de Chillon) is an 1834 oil painting by the French artist Eugène Delacroix. It depicts a scene from the 1816 poem of the same title by the British writer Lord Byron set in the sixteenth century. It portrays the Swiss hero François Bonivard chained in a dungeon of Chillon Castle, straining to reach out towards his younger brother.
It was exhibited at the Salon of 1835 at the Louvre in Paris. It received a mixed reception, but generally admired for its brushwork and energy. It is now in the collection of the Louvre, having been acquired in 1906.
