The Sitwell Baronetcy, of Renishaw in the County of Derby, is a title in the Baronetage of the United Kingdom.^[1] It was created on 3 October 1808 for Sitwell Sitwell, Member of Parliament for West Looe. The Sitwell family had been ironmasters and landowners in Eckington, Derbyshire, for many centuries.

In 1625, George Sitwell (1600–1667), High Sheriff of Derbyshire in 1653, built Renishaw Hall, which remains the family seat. The family were to inherit the estates of two other families; Sacheverell, which died out in 1726, and Reresby, whose heiress married George Sitwell's grandson. George Sitwell's great-great-grandson Francis Hurt Sitwell (1728–1793), father of the first baronet, inherited Barmoor Castle, Northumberland. He was born Francis Hurt, the son of Jonathan Hurt and his wife Katherine Sitwell, heiress of the Sitwell family, and assumed the surname of Sitwell in lieu of his patronymic. The fourth baronet sat as Conservative Member of Parliament for Scarborough. His sons, the fifth and sixth baronets, were both noted poets and authors. Dame Edith Sitwell, his only daughter, was a poet and critic. The seventh Baronet was High Sheriff of Derbyshire in 1983 and a Deputy Lieutenant of the county.

The family seat was originally Renishaw Hall, near Eckington, Derbyshire. The present Baronet until recently resided at Weston Hall near Towcester, Northamptonshire^[2] which was sold in 2021.^[3]
