Emma Bardac (née Moyse; 10 July 1862 – 20 August 1934) was a French singer and the mutual love interest of both Gabriel Fauré and Claude Debussy.

Of Jewish descent, Emma married in the Synagogue of Arcachon,[1][2] aged 17, Parisian banker Sigismond Bardac, by whom she had two children: Raoul, and Régina-Hélène (later Madame Gaston de Tinan (1892–1985)).

[4] In the summer of 1904, after a secret vacation with Emma in Jersey, Debussy wrote to his wife Rosalie ("Lilly") Texier announcing the end of their marriage.

In a documentary film called The Loves of Emma Bardac directed by Thomas Mowrey, the duo-pianists Katia and Marielle Labèque perform a selection of pieces by composers Bizet, Fauré and Debussy.

Bardac is portrayed by Iza Teller in Ken Russell's The Debussy Film released in 1965, starring Oliver Reed in the title role.
