Sibilla Aleramo (born Marta Felicina Faccio; 14 August 1876 – 13 January 1960) was an Italian feminist writer and poet best known for her autobiographical depictions of life as a woman in late 19th century Italy. Aleramo's first book in particular, "Una donna", is considered a classic of Italian literature, and the first outspokenly feminist novel written by an Italian author.
