Luce Fabbri (pen name, Luz de Alba; 1908–2000) was an Italian-Uruguayan anarchist writer, publisher and teacher.

After studying literature at university, she fled Fascist Italy and joined her parents in exile, eventually making her way to Uruguay.

There she witnessed the rapidly changing conditions of the period, began publishing her own journals and writing her own theories on anarchist revolution.

She studied literature at the University of Bologna, writing her dissertation on the work of French anarchist and geographer Élisée Reclus.

She reported that Uruguay rapidly changed from a free country, to one where people lived under "the harassment of continuous surveillance".
