The Willoughby baronetcy, of Baldon House in the County of Oxford, was created in the Baronetage of Great Britain on 8 December 1794 for Christopher Willoughby. An improving agriculturalist, he "promoted the cultivation of swedes in elaborate crop rotations, innovatory methods of tillage and, unfashionably, the use of open fields for growing corn."

The 3rd Baronet sat as Member of Parliament for Yarmouth, Newcastle-under-Lyme and Evesham. The 4th Baronet, involved with the administration of British India represented Leominster in the House of Commons, elected in 1857. The title became extinct on the death of the 5th Baronet in 1918.
