The Brigand Betrayed is an 1828 genre painting by the French artist Horace Vernet. It depicts a bandit lured into a trap by a young woman, as a Papal dragoon waits behind a rock with a pistol. It was produced the year Vernet took up his position as director of the French Academy in Rome, around the same time as his A Roman Herdsman Driving Cattle. He was likely influenced by paintings of bandits produced by Léopold Robert . Today the painting is in the Wallace Collection in London, having been acquired by the Marquess of Hertford in 1870.
