The Chieftain is a two-act comic opera by Arthur Sullivan and F. C. Burnand based on their 1867 opera, The Contrabandista. It consists of substantially the same first act as the 1867 work with a completely new second act. It premiered at the Savoy Theatre on 12 December 1894, under the management of Richard D'Oyly Carte, for a run of 97 performances (by Sullivan's standards, a flop).
The opening cast included Florence St. John, Courtice Pounds, Walter Passmore, Richard Temple, Scott Russell, Florence Perry, Emmie Owen, R. Scott Fishe and Rosina Brandram.
