Giulietta Pezzi (10 February 1810 – 31 December 1878) was an Italian writer and journalist whose work included poetry, four novels, and a five-act play. Born and educated in Milan, she was a devoted follower of Mazzini and active in the Italian republican and unification movements. In her later years she wrote for several newspapers and dedicated herself to the establishment of free public schools in Italy based on Mazzini's educational philosophy. She died in the city of her birth at the age of 71. During her lifetime several art songs were dedicated to her, including Bellini's "Vaga luna, che inargenti".
