Lady Margaret Heathcote (née Yorke; 21 March 1733 – 19 August 1769) was a British aristocrat and poet. The daughter of Philip Yorke, 1st Earl of Hardwicke and husband of Sir Gilbert Heathcote, 3rd Baronet, she wrote several poems throughout her life, some of which were posthumously published.
Despite feeling "utterly incapable [...] of affording either amusement or intelligence", she had a minor career in the arts.[1] She was skilled in poetry during her youth, with one of them appearing in a personal anthology from Lady Mary Capell and another, "Epistle addressed to Lady Grey at Wrest Park" (1747), posthumously appearing in The Gentleman's Magazine, which also published an Italian-language translation she worked on in 1818, and Bell's Classical Arrangement of Fugitive Poetry in the 1780s.[1] She also wrote poems in her letters to her sister Lady Elizabeth Anson and her sister-in-law Lady Amabel Yorke, Countess of Hardwicke, as well as Catherine Talbot.[1] She also did satire, at one point exploring the Seven Years' War in her poetry. In 2024, Jemima Hubberstey called it her "most enduring legacy".[1] Outside of poetry, she had some fine art experience, being a student of Louis Goupy and a drawing teacher of Anne FitzPatrick, Countess of Upper Ossory.[1]
