Mariella Devia (April 12, 1948) is an Italian soprano, well known for performing many roles in the bel canto repertoire.
Born in Chiusavecchia, Devia trained at the Accademia Nazionale di Santa Cecilia in Rome with Iolanda Magnoni. She made her stage debut in Treviso, as Lucia in Lucia di Lammermoor, in 1973, and quickly sang throughout Italy, making her debut at La Scala in Milan in 1987, as Giulietta in I Capuleti e i Montecchi.
On the international scene, she appeared at the Metropolitan Opera, as Lucia, and Carnegie Hall, as Lakmé, in 1979, and made her debut at the Paris Opera and the Aix-en-Provence Festival in 1987, and at the Royal Opera House in London, in 1988.
She was a regular at the Pesaro Festival and at the Festival della Valle d’Itria in Martina Franca, where she won great acclaim in the exhumation of long neglected operas by Rossini, Donizetti, Bellini and other bel canto composers. She is also admired in Mozart operas, especially as Constanze in Abduction from the Seraglio, as well as Verdi’s Gilda and Violetta.
