Lieutenant-General Charles Butler, 1st Earl of Arran (of the second creation), de jure 3rd Duke of Ormonde (4 September 1671 – 17 December 1758) was an Irish peer. His uncle Richard was the 1st Earl of Arran of the first creation. The titles were re-created for Charles in 1693. He was the younger son of Thomas Butler 6th Earl of Ossory and Emilia von Nassau. His paternal grandfather was the 1st Duke of Ormonde and his elder brother was the 2nd Duke of Ormonde.
On 8 March 1693 he was created Earl of Arran (of the second creation) in the Peerage of Ireland. The following year, on 23 January 1694, he was further created Baron Butler, of Weston in the County of Huntingdon, in the Peerage of England. Arran was a Lord of the Bedchamber to King William III, a Lieutenant-General in the Army, Colonel of the 3rd Troop of Horse Guards, Governor of Dover Castle, and Master-General of the Ordnance from 1712 to 1714.
His eldest brother was attainted in 1715 for his treasonous part in the Jacobite rebellion, whereupon all his honours were assumed to have been forfeit. However, it was later ruled that the attainder, enacted by the Parliament of Great Britain, applied only to his British titles (i.e. those in the Peerages of England and Scotland), and not to his Irish titles. Lord Arran therefore legally succeeded on his brother's death on 5 November 1745 as 3rd Duke of Ormonde in the Peerage of Ireland, but was never aware of so succeeding. As such, he was the fourth and last member of the Kilcash branch of the family to succeed to the titles.
