The Jackson, later Duckett Baronetcy, of Hartham House in the County of Wiltshire, was a title in the Baronetage of Great Britain. It was created on 21 June 1791 for the naval administrator and politician George Jackson. He married as his second wife Grace Duckett, daughter of George Duckett. In 1797 he assumed by Royal license the surname of Duckett in lieu of Jackson according to the will of Grace's uncle, Thomas Duckett. He was succeeded by his son by his second wife, the second Baronet, who represented Lymington and Plympton Erle in Parliament. The title became extinct on the death of the third Baronet in 1902.
