Die Herzogin von Chicago is an operetta in two acts, a prologue, and an epilogue. The music was composed by Hungarian composer Emmerich Kálmán with a libretto by Julius Brammer and Alfred Grünwald. It premiered in Vienna at the Theater an der Wien on April 5, 1928, and played for 372 performances. The work was presented in out-of-town tryouts in Newark, New Jersey and Springfield, Massachusetts by the Shuberts in 1929, but it did not make it to Broadway. The piece was forgotten until 1997, when the Lubo Opera Company performed it in concert in New York, after which Light Opera Works of Illinois performed the work in 1998 in a fully staged version with a new translation by Philip Kraus and Gregory Opelka. In 1999, Richard Bonynge made a recording of the work, which revived international interest in it.

Emmerich Kálmán was a Hungarian composer of operettas and a prominent figure in the development of Viennese operetta in the 20th century. Among his most popular works are Die Csárdásfürstin (1915) and Gräfin Mariza (1924). Influences on his compositional style include Hungarian folk music, the Viennese style of precursors such as Johann Strauss II and Franz Lehár, and, in his later works, American jazz. As a result of the Anschluss, Kálmán and his family fled to Paris and then to the United States. He eventually returned to Europe in 1949 and died in Paris in 1953.
