Hugh Denys of Osterley (c. 1440 – 1511) was a courtier of Kings Henry VII and of the young Henry VIII. As Groom of the Stool to Henry VII, he was one of the King's closest courtiers, his role developing into one of administering the Privy Chamber, a department in control of the royal finances which during Denys's tenure of office also gained control over national fiscal policy. Denys was thus a vital player in facilitating the first Tudor king's controversial fiscal policies.
