Eduard Ladislas Kaunitz, baron von Holmberg (1778–1853) was an Austrian military officer, who joined the Argentine revolutionary forces after serving alongside José de San Martín and Carlos María de Alvear during the Argentine War of Independence. He was appointed to the Army of the North under Manuel Belgrano as commander of artillery, and later founded the first sapper corps in the Argentine Army (1813). Kaunitz married Antonia Balbastro, a cousin of Alvear; his son Eduardo Wenceslao also served as an officer under Juan Lavalle.
