Victor François de Montchenu (6 November 1764, Bougé-Chambalud - 12 January 1849, Paris) was a French soldier.
He came from one of the oldest families in the Dauphiné, long devoted to military service. He was admitted to the Ecole des chevaux-légers as a child and in 1775 became sous-lieutenant of the Régiment d'Infanterie du Roi, whose posts were reserved for sons of the noble families most deserving for their nobility and their services. He was a captain in this corps during the Nancy Affair, finding himself beside André Désilles when the latter died by throwing himself in front of a cannon in a vain hope of stopping the battle between the mutinying patriots and the troops of de Bouillé.
Consistently Monarchist, Montchenu quickly decided in 1792 that the royalist cause was irrevocably separated from the nation's cause and left France to join the armée des Princes, serving in it as aide-de-camp to général Livarot. In March 1793 he assisted in the defence of Maestricht against Charles François Dumouriez's force and served as an aide-major in the 1794-95 campaigns in the régiment de Broglie in the pay of England.
Returning to France on the peace of 1814, he was made a croix de Saint-Louis on 13 August that year and was made brevet maréchal de camp on 30 December. His elder brother was sent to Saint Helena in 1815 as commissioner of the French government to keep an eye on the behaviour of Napoleon. Under the Bourbon Restoration he worked as inspector general of the infantry, becoming knight (18 May 1820) then officer (1 May 1821) of the Légion d'honneur. He stopped serving after the July Revolution and was allowed to retire in February 1835.
