Admiral Sir Augustus William James Clifford, 1st Baronet, CB (26 May 1788 – 8 February 1877) was a British Royal Navy officer, court official, and usher of the Black Rod.

Each of his sons, Capt William RN, Robert and Charles succeeded their father in turn as the second, third and fourth (and final) baronets.

Clifford was a patron of the arts, and formed a unique collection of paintings, sculpture, etchings, engravings, and bijouterie.

After this, as captain,[1] he was for many years actively employed in naval duties, being several times mentioned in the London Gazette for his courage in cutting-out expeditions and on other occasions.

His half-brother, the 6th Duke of Devonshire (then Lord Chamberlain), appointed him on 25 July 1832 Gentleman Usher of the Black Rod, which office he held, much to his satisfaction, until his death.
