Admiral of the Fleet Sir Charles Gilbert John Brydone Elliot KCB (12 December 1818 – 21 May 1895) was a Royal Navy officer. As a junior officer he was involved in the bombardment of Acre during the Egyptian–Ottoman War.
During the Second Opium War Eliott led a unit of 300 sailors and marines that successfully breached the walls of Canton and then led another unit that destroyed 23 Chinese war-junks in the estuary South of the city. After that, he led a small squadron of British ships which pursued a fleet of 41 Chinese war-junks at the Battle of Escape Creek: his squadron chased the war-junks upriver and then, once the British ships were grounded as the river narrowed, they chased them in the ships' boats until all the war-junks had been overhauled. He also took part in the larger action, under Commodore Henry Keppel, involving around 100 war-junks at the Battle of Fatshan Creek.
Elliot went on to be Commander-in-Chief, South East Coast of America Station, then Commander-in-Chief, The Nore and finally Commander-in-Chief, Plymouth.
Promoted to rear admiral on 5 August 1861, Elliot became Commander-in-Chief, South East Coast of America Station, with his broad pennant in the second-rate HMS Bombay, in April 1864. This post was based in the Falkland Islands. After HMS Bombay was destroyed by accident in a fire on the River Plate in December 1864, he transferred his flag to the frigate HMS Narcissus.
Promoted to vice admiral on 6 April 1866, Elliot went on to be Commander-in-Chief, The Nore, with his flag in the base ship HMS Pembroke, in July 1870 and, having been promoted to full admiral on 8 February 1873, he became Commander-in-Chief, Plymouth in January 1880. He was advanced to Knight Commander of the Order of the Bath on 24 May 1881, promoted to Admiral of the Fleet on 1 December 1881 and then retired in December 1888.
Elliot died at his home, Brydone House in Bitterne, Southampton, on 21 May 1895.
