A French mezzo-soprano born in Rennes in 1974, Stéphanie d'Oustrac is the great-grandniece of Francis Poulenc and of Jacques de La Presle. She sang from childhood in the Maîtrise de Bretagne before entering the Conservatoire National Supérieur de Musique et de Danse de Lyon, where she won First Prize in singing in 1998. William Christie gave her her first tragédienne roles, quickly placing her at the centre of the French Baroque repertoire (Lully's Médée, Purcell's Dido and Aeneas, Armide, Alcina, L'Incoronazione di Poppea).
Her diction and qualities as an interpreter have made her essential in roles such as Carmen, Berlioz's Béatrice et Bénédict, Pelléas et Mélisande, L'Heure espagnole, La Voix humaine, Dialogues des Carmélites, Werther, Les Troyens, Mignon. Carmen, first sung at the Opéra de Lille in 2010, has become one of her signature roles, reprised at Glyndebourne, the Festival d'Aix-en-Provence in Dmitri Tcherniakov's staging, La Monnaie, La Scala and the Opéra national de Paris.
A regular guest of Opéra-Comique, she has sung there Lully's Atys in 2011, Chabrier's L'Étoile, La Périchole in 2022 in the staging by Valérie Lesort and Christian Hecq, and Concepción in Ravel's L'Heure espagnole in 2024 conducted by Louis Langrée.
