Archibald Acheson, 4th Earl of Gosford

Archibald Brabazon Sparrow Acheson, 4th Earl of Gosford, (19 August 1841 – 11 April 1922) was a British peer.

The son of Archibald Acheson, 3rd Earl of Gosford, he was born at Worlingham Hall, Suffolk, in 1841, and educated at Harrow School; and succeeded to the earldom upon the death of his father in 1864. He was Lord of the Bedchamber to Edward VII, Prince of Wales between 1886 and 1901, and bore the Queen consort's Ivory rod At Edward VII's King's coronation. He became vice-admiral of Ulster, also received the Order of the Dannebrog, and the Order of the White Eagle (Russian Empire). Since there are two United Kingdom peerages (e.g. Baron Worlingham) subsumed in that Irish Earldom, he was entitled to an automatic seat in the House of Lords. He was Lord Lieutenant of Armagh from 1883 to 1920, and served as Vice-Chamberlain of the Household of Queen Alexandra from 1901.

He was Honorary Colonel of the 3rd Battalion of the Royal Irish Fusiliers from 1899, and Vice-Admiral of Ulster. Gosford died in London in 1922, aged 80, and was cremated at Golders Green Crematorium.
