Anne Marie Dubernet known as Cyprienne Dubernet, Madame Olympe Hériot and later Madame Roger Douine (1857 – 5 December 1945), was a French patron of the arts and philanthropist, who was made a Chevalier de la Légion d'Honneur.
She sold corsets at the Grands Magasins du Louvre and on 24 August 1887 married the director-proprietor, Olympe Hériot (1833–1899), to whom she had already borne two children.
In 1903 she redeveloped a site of 1,700 square metres (18,000 sq ft) on the Rue de la Faisanderie in Paris, commissioning architect Hans-Georg Tersling to build a mansion, which she sold in 1928.
Around 1904, she commissioned architect Edouard Arnaud to build the Villa Cypris in Roquebrune-Cap-Martin on the French Riviera.
Thanks to her generosity she was made a Chevalier de la Légion d'Honneur on 5 June 1921 by the order of Marshal Philippe Pétain.
