The I'Anson Baronetcy of Bassetbury was a title in the Baronetage of England. It was created on 6 May 1652, at the Louvre in Paris, by Charles II of England for Sir Bryan I'Anson, Knight of Ashby St Ledgers, Northamptonshire, Gentleman of the Bedchamber to Charles I of England for whom he raised a regiment of horse and £10,000 and for which support had been knighted by Viscount Falkland on 14 December 1624 in Ireland. The baronetcy became extinct on the death of the seventh Baronet in 1800.
