Eugenia Mantelli (1860- 3 March 1926) was an Italian opera singer who had a prolific career in Europe, the United States, and South America from the 1880s through the early part of the twentieth century.
She possessed a flexible warm voice with a wide vocal range that, while focusing mostly within the mezzo-soprano repertoire, enabled her to sing roles normally associated with contraltos and sopranos.
She made her professional opera debut at the Teatro Nacional de São Carlos in Lisbon as Urbain in Giacomo Meyerbeer's Les Huguenots in 1883.
[2] In 1894 Mantelli joined the roster of the Metropolitan Opera in New York City, making her first appearance there as Amneris in Verdi's Aida on 23 November.
Although she returned to the Met briefly in 1902 and appeared in a few vaudeville productions during the early 1900s, she spent most of her remaining career performing at the Teatro Nacional de São Carlos.
