François Mireur (February 5, 1770 – July 9, 1798) was a French general who is notable for having sung the "War Song for the Army of the Rhine", later known as La Marseillaise, in 1792 when he volunteered for the newly created republican army.

That year, he sang Rouget de Lisle's war song when he was headed to Marseilles to organize and lead volunteers from nearby towns.

During the war, he fought at the Battle of Valmy and later served in the Italian Campaign of Napoleon, twice refusing the rank of general.

In 1798, he was promoted to general and served alongside Louis Desaix in the Egyptian Campaign, where he fought the Mamelukes and Ottomans.

While riding a newly purchased Arabian stallion, after only a short distance, he was ambushed by three Mamelukes, and killed before he could call for help.
