Marguerite d'Alvarez (c. 1884 – 18 October 1953) was an English contralto, born Margarita Amelia Alvarez de Rocafuerte.

[6] After further studies in Paris she made her first American appearances with the Manhattan Opera Company in 1909[6] as Fidès in Giacomo Meyerbeer's Le prophète.

[7] D'Alvarez subsequently appeared at leading European opera houses such as Covent Garden, and also sang in Chicago and Boston, and made a tour of Australia[5] and New Zealand[8] after World War I.

[10] In 1929, she headlined in a "Pan-American Program" in Washington, D.C.[11] In 1926, d'Alvarez defended jazz from its European detractors, including composers Richard Strauss and Pietro Mascagni.

"[12] D'Alvarez made several acoustic recordings in New York, including arias from her operatic repertoire and Spanish songs by Falla, Chapi and Tabuyo.
