Mary Wilson, Baroness Wilson of Rievaulx

Gladys Mary Wilson, Baroness Wilson of Rievaulx (; 12 January 19166 June 2018) was an English poet and the wife of Harold Wilson, who twice served as British prime minister. She was the first British prime minister's spouse to become a centenarian, living to the age of .

Life Gladys Mary Baldwin was born in Diss, Norfolk, the daughter of the Reverend Daniel Baldwin, who was a Congregationalist minister. She attended boarding school at Milton Mount College leaving aged 16 to attend a secretarial course for two years. She was employed as a stenographer at Lever Brothers in Port Sunlight before marrying Harold Wilson on New Year's Day 1940 at Mansfield College, Oxford.

In 1970, her volume of poetry Selected Poems was published, and, in 1976, Mary Wilson was one of three judges of the Booker Prize, the other judges being Walter Allen and Francis King. According to the Dictionary of National Biography entry for Harold Wilson, written by Roy Jenkins, Wilson was not satisfied with life in politics. It was this detachment which gave the Private Eye spoof "Mrs Wilson's Diary", the supposed diary of Wilson, written in the style of the BBC's daily radio serial Mrs Dale's Diary, a spurious look of authenticity.

In 2010, at the age of 94, she attended the funeral of Michael Foot. Three years later, at the age of 97, she accepted an invitation to the funeral of Margaret Thatcher.

Death Wilson died following a stroke at St Thomas' Hospital in London on 6 June 2018, at the age of 102, having outlived her husband by 23 years. The longest-lived spouse of a British prime minister, she was the first to live beyond the age of 100. A private service followed by cremation took place on mainland Britain, and her ashes were buried with her husband at Old Town Churchyard in St Mary's, Isles of Scilly.
