Arthur Gore, 5th Earl of Arran

Arthur Saunders Gore, 5th Earl of Arran KP (6 January 1839 – 14 March 1901), known as Viscount Sudley from 1839 to 1884, was an Anglo-Irish peer and diplomat.

Arran was the eldest son of Philip Yorke Gore, 4th Earl of Arran, and Elizabeth Marianne Napier, daughter of General Sir William Francis Patrick Napier, KCB. He was educated at Eton College, and subsequently entered the diplomatic service.

He was appointed High Sheriff of Donegal in 1863.He was an Attaché at the British embassies in Hanover, Stuttgart, Lisbon and Paris as well as a Special Commissioner for Income Tax from 1865 to 1881 and a Commissioner of Customs from 1883 to 1884. In 1884 he succeeded his father as fifth Earl of Arran but as this was an Irish peerage it did not entitle him to a seat in the House of Lords. However, later the same year he was created Baron Sudley, of Castle Gore in the County of Mayo, in the Peerage of the United Kingdom, which gave him an automatic seat in the upper chamber of Parliament. He later served as Lord Lieutenant of County Mayo from 1889 to 1901 and was made a Knight of the Order of St Patrick in 1898.

Lord Arran married, firstly in 1865, Honourable Edith Elizabeth Henrietta Jocelyn (1845–1871), daughter of Robert Jocelyn, Viscount Jocelyn. They had one son and three daughters before she died early in 1871. Among the children were:

• Arthur Jocelyn Charles Gore (1868–1958), who succeeded as 5th Earl of Arran.
• Lady Esther Georgiana Caroline Gore (1870–1955), wife of the 2nd Viscount Hambleden
