The siege of Mainz was a short engagement at the beginning of the War of the First Coalition. The victorious French army of Custine seized the town on October 21, 1792, after three days of siege. The French occupied Mainz, and tried to install the Republic of Mainz there.

After the declaration of war by France against the Archduchy of Austria (1792) and the declaration against Mainz on 21 July 1792, Comte de Custine was given command of the Army of the Rhine to replace Nicolas Luckner, and in September occupied the southern Rhineland about the cities of Speyer and Worms. The regiments of the Duke of Nassau left the Fortress of Mainz on October 5.
