Charlotte du Val d'Ognes, born Marie Joséphine Charlotte du Val d'Ognes, (1786 - 1868) was a French aristocrat who is notable for being the subject of the 1801 portrait painting Portrait of Charlotte du Val d'Ognes by Marie-Denise Villers.
Marie Joséphine Charlotte du Val d'Ognes was born into the French aristocratic Val d'Ognes family in 1786, making her a pre-French Revolution aristocrat.
In 1801, d'Ognes, aged 15 or 16, sat for a portrait, which was probably painted by Marie-Denise Villers, who was a friend of d'Ognes. This portrait remains one of the few surviving glimpses into Charlotte du Val d'Ognes's life.
d'Ognes died in 1868 aged 81 or 82.
