Anna, Comtesse Mathieu de Noailles (15 November 1876 – 30 April 1933), was a Romanian-French writer.
In 1897 she married Mathieu Fernand Frédéric Pascal, de Noailles (1873–1942), the fourth son of the 7th Duke de Noailles. The couple soon became the toast of Parisian high society. They had one child, a son, Count Anne-Jules de Noailles (1900–1979).
Anna de Noailles wrote three novels, an autobiography, and many collections of poetry. She had friendly relations with the intellectual, literary and artistic elite of the day including Marcel Proust, Francis Jammes, Colette, André Gide, Frédéric Mistral, Robert de Montesquiou-Fezensac, Paul Valéry, Jean Cocteau, Pierre Loti, Paul Hervieu, and Max Jacob.
So popular was Anna de Noailles that various notable artists of the day painted her portrait, including Antonio de la Gandara, Kees van Dongen, Jacques Émile Blanche, and the British portrait painter Philip de Laszlo. In 1906 her image was sculpted by Auguste Rodin; the clay model can be seen today in the Musée Rodin in Paris, and the finished marble bust is on display in New York’s Metropolitan Museum.
Anna de Noailles was the first woman to become a Commander of the Legion of Honor, the first woman to be received in the Royal Belgian Academy of French Language and Literature, and she was honored with the “Grand Prix” of the Académie Française in 1921.
