Duke of Suffolk was a title that has been created three times in the peerage of England.
The dukedom was first created for William de la Pole, who had already been elevated to the ranks of earl and marquess, and was a powerful figure under Henry VI.
The second creation was for Charles Brandon, a favourite of Henry VIII; his two sons successively inherited the title, but left no more heirs.
The third creation of the dukedom of Suffolk was for Henry Grey, 3rd Marquess of Dorset, in 1551. The duke also held the title Baron Ferrers of Groby (1300). These titles became forfeit when the duke was attainted in 1554.
