Fiesco (full title – Die Verschwörung des Fiesco zu Genua, or Fiesco's Conspiracy at Genoa) is the second full-length drama written by the German playwright Friedrich Schiller. It is a republican tragedy based on the historical conspiracy of Giovanni Luigi Fieschi against Andrea Doria in Genoa in 1547. Schiller began it after the 1782 premiere of his first play, The Robbers, and dedicated it to his teacher Jakob Friedrich von Abel. It has 75 scenes, which is more than Goethe's highly popular Götz von Berlichingen. It premiered in Bonn in 1783 at the Hoftheater.
The play was the basis for the 1921 German silent film The Conspiracy in Genoa directed by Paul Leni.
