Mady Mesplé (born 7 March 1931) is a French opera singer, the leading high coloratura soprano of her generation in France, sometimes heralded as the successor to Mado Robin.
Mady Mesplé was born in Toulouse, France, and studied piano and voice at the music conservatory of her native city, graduating with a gold medal. She played the piano in a local ballroom orchestra for a while, and later left for Paris for complementary voice lessons with French soprano Janine Micheau.
Mesplé made her professional debut in Liège in January 1953, as Lakmé, a role with which she remained closely associated throughout her career, singing it an estimated 145 times. Lakmé was also her debut role at La Monnaie in Brussels in 1954. She quickly established herself in the standard lyric and coloratura roles of the French repertoire, such as Olympia in Les contes d'Hoffmann, Philline in Mignon, Leila in Les pêcheurs de perles, Juliette in Roméo et Juliette, Ophélie in Hamlet, Dinorah, Manon, Sophie in Werther, etc.
She made her debut at the Aix-en-Provence Festival in 1956, as Zémire in Grétry's Zémire et Azor. The same year saw her debut at the Opéra-Comique as Lakmé. Her Palais Garnier debut took place in 1958, as Constance in Francis Poulenc's Dialogues des Carmélites. Full consecration came at that opera house, in 1960, when she took over from Joan Sutherland in a new production of Lucia di Lammermoor. Other Italian roles included Amina in La Sonnambula, Rosina in Il barbiere di Siviglia, Norina in Don Pasquale and Gilda in Rigoletto. She also sang a few German roles with success, notably the Queen of the Night in Die Zauberflöte, Sophie in Der Rosenkavalier, and a much-acclaimed Zerbinetta in Ariadne auf Naxos in Aix-en-Provence in 1966.
