Franz von Suppè (until recently usually incorrectly von Suppé, né Francesco Ezechiele Ermenegildo de Suppè; 18 April 1819 – 21 May 1895) was an Austrian composer of light operas and other theatre music. He came from the Kingdom of Dalmatia, Austro-Hungarian Empire (now part of Croatia). A composer and conductor of the Romantic period, he is notable for his four dozen operettas.

Until recently, his name was usually incorrectly spelled Suppé with an acute accent or even without an accent as in the incorrect parish register entry, despite his father, grandfather, great grandfather, and great-great grandfather being recorded as Suppè with a normal Italian grave accent.

Grove Music Online and Encyclopædia Britannica and Die Musik in Geschichte und Gegenwart have articles dating from 2001 to 2016 that already mention the corrected spelling but do not yet report on more recent research by Andreas Weigel and others that are already incorporated in the more recent article in the Oesterreichisches Musiklexikon, for example that Demelli is incorrect, that his mother's maiden name is Jandovsky or Jandowsky (not Landovsky), and that Suppè lied about or embellished very many things in his biography to a degree quite unique in music history (for example about his education and when he met his wives).
