Jean-Gabriel Saint-Martin began his musical journey with the Children’s Chorus of the Paris Opera under Francis Bardot, and studied singing with Nicole Fallien, his first teacher. After earning a Master’s degree in Private Law, he entered the Conservatoire National Supérieur de Musique de Paris, studying with Pierre Mervant, and later worked with Michèle Ledroit, Noëlle Barker and Lionel Sarrazin. In 2011, he was named “Classical Revelation – Opera Artist” by the ADAMI. He was subsequently a member of the Opera Studio of the Opéra National du Rhin and of the New Studio of the Opéra de Lyon.

Since then, he has performed on many of France’s leading stages — Paris, Strasbourg, Marseille, Lille, Dijon, Rennes, Saint-Étienne, Versailles, Tours — and at major festivals such as the Festival d’Aix-en-Provence and the Radio France Occitanie Festival. He collaborates regularly with renowned baroque ensembles including Le Concert d’Astrée (Emmanuelle Haïm), Les Musiciens du Louvre (Marc Minkowski), Le Poème Harmonique (Vincent Dumestre), Opera Fuoco (David Stern) and Le Concert Spirituel (Hervé Niquet).

On stage, he is particularly noted for his interpretations of Mozart roles — Don Giovanni, Figaro, Guglielmo, Don Alfonso and Papageno. He has appeared at the Théâtre des Champs-Élysées (Manon alongside Juan Diego Flórez), the Opéra Royal de Versailles (Don Giovanni, La Caravane du Caire, Richard Cœur de Lion), and the Philharmonie de Paris in Mozart’s Great Mass in C minor with the ONDIF and the Radio France Choir.

Recent performances include Papageno (Die Zauberflöte) at the Opéra de Tours, Hortensius (La Fille du Régiment) at the Opéra Royal de Versailles and Festival Napa Valley (USA), and Le Dancaïre (Carmen) at the Opéra de Nice.

Upcoming engagements include La Périchole in Opéra de Saint-Etienne, Faust at the Opéra de Tours and the Opéra Royal de Versailles, as well as La Fille du Régiment at the Opéra de Tours for the end of the 2025-2026 season.
