George Percy, 5th Duke of Northumberland PC (22 June 1778 – 22 August 1867), styled Lord Lovaine between 1790 and 1830 and known as the Earl of Beverley between 1830 and 1865, was a British Tory politician.

He succeeded to his peerage on 12 February 1865, after the death of his childless cousin Algernon Percy.

[3] Northumberland was returned to parliament for the rotten borough of Bere Alston in 1799, a seat he held until 1830,[4] when he succeeded his father in the earldom and entered the House of Lords.

[1] He was sworn of the Privy Council in January 1842[5] and was appointed Captain of the Yeomen of the Guard (Deputy Chief Whip in the House of Lords[citation needed]) by Sir Robert Peel,[6] a post he held until the government fell in 1846.

He was buried in the Northumberland Vault, within Westminster Abbey,[9] and was succeeded in the dukedom by his eldest surviving son, Algernon.
