There have been two baronetcies created for members of the Barnardiston family, both in the Baronetage of England. Both creations are extinct. The Barnardiston Baronetcy, of Ketton in the County of Suffolk, was created in the Baronetage of England on 7 April 1663 for Thomas Barnardiston, Member of Parliament for Bury St Edmunds and Suffolk and the son of Sir Nathaniel Barnardiston. The second Baronet was Member of Parliament for Grimsby and Sudbury. The title became extinct on the death of the sixth Baronet in 1745.
