There have been three creations of baronets with the surname Duff, all in the Baronetage of the United Kingdom.
The Assheton-Smith, later Duff Baronetcy, of Vaynol Park in the County of Carnarfon, was created in the Baronetage of the United Kingdom on 1 August 1911 for Charles Garden Assheton-Smith.
The Duff Baronetcy, of Hatton in the County of Aberdeen, was created in the Baronetage of the United Kingdom on 3 July 1952 for Garden Beauchamp Duff.
He was a descendant of Garden William Duff, whose younger brother Robert George Duff was the ancestor of 1911 baronets of Vaynoll Park.
The title became extinct on Sir Garden Beauchamp Duff's death in 1952.
