Walter Butler, 1st Marquess of Ormonde KP (5 February 1770 – 10 August 1820) was an Irish peer and politician. Partly to sustain his extravagant lifestyle, Walter gave up his hereditary right to the grant of the prisage of the wines of Ireland for an enormous sum of money. The right had been made to the 4th Chief Butler of Ireland by Edward I of England. Between 1789 and 1796, he sat for Kilkenny County in the Irish House of Commons.
He was the son of John Butler, 17th Earl of Ormonde and Frances Susan Elizabeth Wandesford. He married Anna Maria Catherine Clarke, daughter of Joseph Hart Pryce Clarke, on 17 March 1805. As they had no children, the Marquisate became extinct; the Earldom of Ormonde, however, devolved upon his brother James Wandesford Butler, who subsequently became first Marquess of Ormonde in the peerage of the United Kingdom.
