Luigi Capello (1859–1941) was an Italian army officer.
He took part to the Italo-Turkish War (1911–12), where he distinguished himself. During World War I he was the commander of several Army Corps, then, since June 1917, of the II Army, and led the Italian troops that captured Gorizia and the Bainsizza Plateau. Later, he was removed from command after the Italian defeat at Caporetto (October–November 1917).
After the war, at first he joined the National Fascist Party, from which he was expelled in 1923 due to his Masonic connections. Later he was involved in the planning of an attempt to assassinate Benito Mussolini, for which he was tried and sentenced to jail in 1927; he was released in 1936, after serving eleven years.
