John Butler of Kilcash (died 1570) was an Irish landowner and soldier. A younger son of James Butler, 9th Earl of Ormond and brother of Thomas Butler, 10th Earl of Ormond, he received Kilcash Castle as appanage. He fought in the Desmond–Ormond conflict and was badly wounded in 1563, just before the Battle of Affane. He was the start-point of the Kilcash branch of the Ormonds and the father of Walter Butler, 11th Earl of Ormond.
