George Delaval (c. 1667 – 22 June 1723) was an English naval admiral and diplomat.
He was of a junior branch of the Delaval family, the son of George Delaval of North Dissington, Northumberland. His father left him a legacy of only £100 but he went on to make a large fortune from his naval and diplomatic career.
He joined the Royal Navy and by 1693 had achieved the rank of 3rd lieutenant aboard HMS Lenox. In 1698 he travelled to North Africa to negotiate the release of British prisoners and on his return as Captain Delaval in May 1700 he took command of the newly commissioned 4th rate man of war HMS Tilbury.
Diplomatic and political career
In 1716 he purchased for £5000 the forfeited estate of the Shafto family at Bavington Hall, Northumberland, and in 1718 he bought the ancient seat of the Delaval family at Seaton Delaval from his impoverished cousin, Sir John Delaval, 3rd Baronet. He retained the services of the architect Sir John Vanbrugh and began an ambitious rebuilding of Seaton Delaval Hall. He did not live to see the new house completed; in 1723, at the age of 55, he died as a result of falling off his horse. The site of the accident was marked by the erection of an obelisk, the base of which survives to the west of the hall, next to the turning to New Hartley.
