Eugénie de Gramont (17 September 1788, Versailles – 19 November 1846, Paris) was a French nun of the Society of the Sacred Heart.
Her aristocratic mother also joined it a few years afterwards, and made her novitiate under the guidance of her own daughter.
In 1815, despite her relative youth and the drawback of a slight physical deformity, de Gramont was placed in charge of the first school of the Sacred Heart, opened in Paris, Rue des Postes, afterwards transferred to the Rue de Varenne.
The school flourished under her care and, after a short interruption of her work by the revolution of 1830, she was sent back to govern the house as superioress and continued to do so until her death in 1846.
After the death of the Count de Gramont d'Aster, his widow was for a time in straitened circumstances, and maintained herself and her child by teaching.
