Marie-Thérèse Figueur (Talmay, 17 January 1774 – Paris, hospice des Petits Ménages, 4 January 1861), known by the nom de guerre Sans-Gêne (literally "unconstrained"), was a French heroine who fought in the French Revolutionary Wars and Napoleonic Wars.
In contrast with most female soldiers before the twentieth century, she did not disguise her gender when she enlisted, serving for twenty-two years under her own name in the French Revolutionary Army and the Grande Armée.
