The siege of Thionville saw an unsuccessful attempt to conquer the French stronghold of Thionville by the Austro-royalists during the War of the First Coalition.
It began at Thionville on 24 August 1792. A coalition force of 20,000 Austrians and 16,000 French Royalist troops under Friedrich Wilhelm, Fürst zu Hohenlohe-Kirchberg failed to take the town, commanded by Georges Félix de Wimpffen, and raised the siege on 16 October. One of the French royalist troops was François-René de Chateaubriand, who was wounded in the battle.
In the aftermath of the siege the National Convention declared that Thionville had "deserved well of the fatherland" - it named Place de Thionville and Rue de Thionville in Paris after the victory.
Louis-Emmanuel Nadine created the lyrical drama Siége de Thionville in 1793.
