The Contrabandista, or The Law of the Ladrones, is a two-act comic opera by Arthur Sullivan and F. C. Burnand. It premiered at St. George's Hall, in London, on 18 December 1867 under the management of Thomas German Reed, for a run of 72 performances. There were brief revivals in Manchester in 1874 and America in 1880. In 1894, it was revised into a new opera, The Chieftain, with a completely different second act.
