The Osborne, later Osborn Baronetcy, of Chicksands in the County of Bedford, is a title in the Baronetage of England. It was created on 11 February 1662 for John Osborne, subsequently Remembrancer to the Treasury from 1674 to 1698. The baronetcy was in recognition of the sufferings the family had suffered for its support of Charles I. Osborn was the son of Sir Peter Osborne, Governor of Guernsey, great-grandson of Peter Osborne, who acquired the family seat of Chicksands Priory in 1576 and was Remembrancer of the Treasury to Henry VIII, Keeper of the Privy Purse to Edward VI and Commissioner of Ecclesiastical Affairs to Elizabeth I. The third Baronet was the son of John Osborn, eldest son of the second Baronet, who altered the spelling of the family surname to Osborn to avoid confusion with the family of the Duke of Leeds. The third Baronet was Governor of New York and Member of Parliament for Bedfordshire. The fourth Baronet was a General in the British Army and also represented Northampton, Bossiney, Penrhyn and Horsham in the House of Commons. The fifth Baronet was Member of Parliament for four constituencies and served as a Lord of the Admiralty under the Earl of Liverpool.
Dorothy Osborne (1627-1695) was the daughter of Sir Peter Osborne and sister of the first Baronet.
