Coningsby Sibthorp DCL (c. 1706 – 20 July 1779) was an English Tory politician who sat in the House of Commons for the borough seat of Lincoln on variously between 1741 and 1768. Sibthorp was a member of the Sibthorp family of Canwick Hall in Lincolnshire which produced several Tory Members of Parliament between the early 18th-century and mid 19th-century, in addition to several botanists. Like the vast majority of Tory Members of Parliament during the Whig supremacy Sibthorp never held ministerial office, maintaining his political independence and Tory principles throughout his political career. On one occasion, however, Sibthorp did serve as the High Sheriff of Lincolnshire.
