Brigadier-General Hanway Robert Cumming (1867 – 5 March 1921) was an officer in the British Army. He fought in the Second Boer War, and in France during the First World War. He was awarded the Distinguished Service Order and appointed an Officer in the French Légion d'honneur. During the Irish War of Independence he was commander of British troops in County Kerry. He was killed at the Clonbanin Ambush, possibly the highest-ranking British officer to be killed in that war.
