Egmont, Op. 84, by Ludwig van Beethoven, is a set of incidental music pieces for the 1787 play of the same name by Johann Wolfgang von Goethe. It consists of an overture followed by a sequence of nine pieces for soprano, male narrator and full symphony orchestra. (The male narrator is optional; he is not used in the play and does not appear in all recordings of the complete incidental music.) Beethoven wrote it between October 1809 and June 1810, and it was premiered on 15 June 1810.

The subject of the music and dramatic narrative is the life and heroism of a 16th-century Dutch nobleman, the Count of Egmont. It was composed during the period of the Napoleonic Wars, at a time when the French Empire had extended its domination over most of Europe. Beethoven had famously expressed his great outrage over Napoleon Bonaparte's decision to crown himself Emperor in 1804, furiously scratching out his name in the dedication of the Eroica Symphony. In the music for Egmont, Beethoven expressed his own political concerns through the exaltation of the heroic sacrifice of a man condemned to death for having taken a valiant stand against oppression. The Overture later became an unofficial anthem of the 1956 Hungarian revolution.
