Charles Brandon, 3rd Duke of Suffolk (12 October 1537[1] – 14 July 1551), known as Lord Charles Brandon until shortly before his death, was the son of the 1st Duke of Suffolk and the suo jure 12th Baroness Willoughby de Eresby.

His father had previously been married to Mary Tudor, sister of King Henry VIII.

Following Mary's death, he had married Lady Willoughby de Eresby, who had been originally intended as the bride of his son Henry.

[2] He died of the sweating sickness one hour after the same disease claimed his elder brother Henry (who had succeeded their father as 2nd Duke of Suffolk in 1545), and because of this holds the record for the shortest tenure of a British peerage.

[3] The humanist intellectuals Thomas Wilson and Walter Haddon wrote a life of Suffolk and his older brother shortly after their death.
