Der Graf von Luxemburg (The Count of Luxembourg) is an operetta in three acts by Franz Lehár to a German libretto by Alfred Willner, Robert Bodanzky, and Leo Stein. A Viennese take on bohemian life in Paris at the beginning of the 20th century, the story revolves around an impoverished aristocrat and a glamorous opera singer who have entered into a sham marriage without ever seeing each other and later fall in love at first sight, unaware that they are already husband and wife.
It premiered at the Theater an der Wien, in Vienna, on 12 November 1909 and was an immediate success, being revived in Germany and translated into other languages for successful foreign productions including in France as Le comte de Luxembourg and in English-speaking countries as The Count of Luxembourg. It has remained in the repertory until the present day, especially in German-speaking countries, and several film and stage adaptations have been produced. The piece was recorded with the original Viennese cast and has since been recorded in several languages.
