Montserrat Caballé (12 April 1933, Barcelona, Spain — 6 October 2018, Barcelona) was a Spanish operatic soprano, admired for her versatility and phrasing and for her performances in the operas of Giuseppe Verdi, Gaetano Donizetti, and Richard Strauss.

She began her studies as a child at the Conservatori Liceu in Barcelona with Eugenia Kenny and later continued with Napoleone Annovazzi and Conchita Badía. In 1956 she joined the Basel Opera, in which later that year she had her first major role, as Mimi in Giacomo Puccini’s La Bohème. In 1959 she became a principal singer with the Bremen Opera. Her repertory soon included 46 Italian, German, and French roles.

In 1964 Caballé made a sensational debut in Mexico City in Jules Massenet’s Manon. In the following year she gave a highly successful concert performance of Gaetano Donizetti’s Lucrezia Borgia at Carnegie Hall in New York City, sang the parts of the Countess in Wolfgang Amadeus Mozart’s Le nozze di Figaro and the Marschallin in Strauss’s Der Rosenkavalier at the Glyndebourne Festival in East Sussex, and made her debut at the Metropolitan Opera in New York City as Marguerite in Charles Gounod’s Faust.

She performed in leading opera houses of the world and gave many recitals, most notably of Spanish songs. She is also known for a pop experience with Queen’s vocalist Freddie Mercury, with whom she recorded “Barcelona”, the Barcelona’s Olympic Games anthem, in 1992.
