James FitzJames Butler, 2nd Duke of Ormonde, (1665–1745) was an Irish statesman and soldier. He was the third of the Kilcash branch of the family to inherit the earldom of Ormond. Like his grandfather, the 1st Duke, he was raised as a Protestant, unlike his extended family who held to Roman Catholicism. He served in the campaign to put down the Monmouth Rebellion, in the Williamite War in Ireland, in the Nine Years' War and in the War of the Spanish Succession but was accused of treason and went into exile after the Jacobite rising of 1715.

Butler is the name of a noble family whose members were, for several centuries, prominent in the administration of the Lordship of Ireland and the Kingdom of Ireland. They rose to their highest prominence as Dukes of Ormonde. The family has produced multiple titles such as Baron Cahir, Baron Dunboyne, Viscount Ikerrin, Viscount Galmoye, Viscount Mountgarret, Viscount Thurles, Earl of Carrick, Earl of Kilkenny, Earl of Ormond, Earl of Ossory, Marquess of Ormonde and Duke of Ormonde. Variant spellings of the name include le Boteler and le Botiller. The Butlers were descendants of Anglo-Norman lords who participated in the Norman invasion of Ireland in the 12th century. The surname has its origins in the hereditary office of "Butler (cup-bearer) of Ireland", originating with Theobald Walter, 1st Chief Butler of Ireland. The arms of later family members depicted three cups in recognition of their original office.
