Augustine Allix (4 May 1823 − 15 January 1901) was a French singer, pianist and teacher of music and song, having been part of the close entourage of the family of Victor Hugo during the latter's exile to Jersey and Guernsey.

Born in Fontenay-le-Comte on 4 May 1823,[1] Augustine Allix, together with her sisters Thérèse-Mirza, Bathilde, Eudoxie and Céline, ran an institution for young girls in their home town between 1842 and 1847.

[3] A student of the singer and educator François Delsarte, Allix began a singing career on the Parisian stage that same year.

[4] Between 1847 and 1853, she performed several melodies and compositions, including La Danse au bois, a romance composed by Oscar Comettant and written by Adolphe Favre Le Lac by Louis Niedermeyer, La Sympathie by Charles Haas [fr], Ruth et Booz, a poem composed by Eugène Villemain and written by Antoine Elwart, Le Mariage de Hasard, composed by Eudoxie Péan de la Roche-Jagu.

She continued to give concerts and piano lessons for the outcasts and remained very close to the Hugos, being a regular visitor to their home at Hauteville House.
