Stephen Moore, 2nd Earl Mount Cashell (19 March 1770 – 27 October 1822), styled Lord Kilworth between 1781 and 1790, was an Anglo-Irish politician.
Moore was the eldest son of Stephen Moore, 1st Earl Mount Cashell, and Lady Helena Rawdon, daughter of John Rawdon, 1st Earl of Moira. He became known by the courtesy title Lord Kilworth after his father was elevated to an earldom in 1781.[1] He was returned to the Irish House of Commons for Clonmel in May 1790, but was forced to resign his seat after only a few days on the death of his father.[2] As the holder of an Irish peerage, Lord Mount Cashell was not allowed an automatic seat in the English House of Lords on the formation of the Union in 1800. However, in 1815 he was elected an Irish representative peer, replacing the deceased Earl of Westmeath, and was able to take his seat in the House of Lords.[3]
