The Duncan baronetcy, of Horsforth Hall in the Parish of Guiseley, West Riding of the County of York, was created in the Baronetage of the United Kingdom on 9 December 1905 for William Duncan. He had contested Pudsey as a Conservative in the 1885 General Election, but lost to Briggs Priestley. The title became extinct on the death of the 3rd Baronet in 1964, leaving no heir.
