Emilio De Bono (19 March 1866 – 11 January 1944) was an Italian general, fascist activist, marshal, war criminal, and member of the Fascist Grand Council (Gran Consiglio del Fascismo). De Bono fought in the Italo-Turkish War, the First World War and the Second Italo-Abyssinian War. He was one of the key figures behind Italy's anti-partisan policies in Libya, such as the use of poison gas and concentration camps, which resulted in the deaths of tens of thousands of civilians and have been described as genocidal. Early life and career De Bono was born in Cassano d'Adda, a son of Giovanni de Bono and descendant of the Counts of Barlassina, and Elisa Bazzi. His family "suffered under the Austrian yoke". He entered the Royal Italian Army (Regio Esercito) in 1884 as a second lieutenant, fought in the Italo-Ethiopian War of 1887-1889, and had worked his way up to the General Staff by the start of the Italo-Turkish War in 1911.

He was also the author of a popular patriotic song, Monte Grappa tu sei la mia patria ("Mount Grappa, you are my Fatherland").
