Emma Marcy Raymond (pseudonym, Salvator Sylvain; 1839 – November 7, 1913) was an American musician, composer, and author of operetta, songs and piano music.

Her father was a graduate of the University of Pennsylvania and later a homeopathic specialist, who apparently lived for many years on Fifth Avenue on the site opposite Tiffany's.

She studied the piano with Louis Moreau Gottschalk and Raccoman, vocal music with Giorgio Ronconi, and counterpoint and harmony with the best German masters.

She was the author of Spanish Bolero in E Flat; Ave Maria, Had I My Wish, and others of lesser importance, but equally well-written, such as the Manhattan Beach Polka, Straight Tip Waltz, and Toboggan Galop.

[4] In June of that year, the Times Herald of Port Huron, Michigan reported that Raymond had lost nearly US$15,000 through the failure of this opera.

[10] Subsequently, Raymond wanted Harry Paulton to write the libretto for a comic opera, the music of which she would furnish.

[11] In 1891, she published "The Sheik; a comic opera in 3 acts", libretto by Harry and Edward Paulton, music by Salvator Sylvain (Raymond's pseudonym).

During the winter of 1896–1897, she commissioned the artist Adolfo Müller-Ury to paint a portrait of the bass-baritone Pol Plançon for her, which was subsequently exhibited in March 1897 at the Durand-Ruel Galleries in New York.
