Sir Sacheverell Sitwell (November 15, 1897 ?October 1, 1988) was an English writer, best known as an art critic and writer on architecture, particularly the baroque. He was the younger brother of Edith Sitwell and Osbert Sitwell; later in life he became more reticent about associating himself with the publicity attaching to the Sitwells collectively, travelling and concentrating on writing. He became the 6th baronet, inheriting the title when Osbert died in 1969. He was made a Companion of Honour in 1984. His main residence was Weston Hall, Northamptonshire, the family home. He was born in Scarborough, Yorkshire and brought up in Derbyshire; he was educated at Eton College and Balliol College, Oxford. In World War I he served from 1916 in the British Army, in the Grenadier Guards. After the war he went to Balliol but did not complete a degree; and was heavily involved in Osbert and Edith's projects In 1925 he married a Canadian, Georgia Doble. Constant Lambert set to music The Rio Grande, one of his poems, and it was performed and broadcast in 1929. Because his poetry was so severely criticised by those who disliked the Sitwells in general, and although Cantos and Giant Art is a work of very considerable impact, he refused to publish any of his poems for many years. In 1967 Derek Parker published a selection of his poems in the summer edition of Poetry Review, including his elegy for his beloved sister Edith.
