William Stuart PC (15 March 1755 – 6 May 1822) was an Anglican prelate who served as the Bishop of St David's in Wales from 1794 to 1800 and then Archbishop of Armagh in Ireland from 1800 until his death.
Stuart was the son of John Stuart, 3rd Earl of Bute (Prime Minister of Great Britain 1762–1763) and Mary Wortley-Montagu. There is a painting in the Tate Gallery in London of him aged 12 stealing eggs and chicks from a bird's nest.
He was educated at Winchester College and St John's College, Cambridge.
On 3 May 1796, William married Sophia Penn, daughter of Thomas Penn, and had three children:
In 1793 he was appointed Canon of the fourth stall at St George's Chapel, Windsor Castle, a position he held until 1800.
He was consecrated Bishop of St David's on 12 January 1794. Six years later, he was nominated Archbishop of Armagh on 30 October 1800 and appointed by letters patent on 22 November 1800.
He died in London on 6 May 1822, aged 67, as a result of having accidentally taken an improper medicine.
He was buried at his family's seat, Luton Hoo in Bedfordshire.
In St Patrick's Anglican Cathedral in Armagh there is a full-length marble figure of the Archbishop in the attitude of prayer, sculpted by Sir Francis Chantrey. Beneath it is the following Latin inscription:
