George John Frederick West, Viscount Cantelupe (26 April 1814 – 25 June 1850), was a British politician.
Styled Viscount Cantelupe from birth, he was the eldest son of George Sackville-West, 5th Earl De La Warr, by Lady Elizabeth Sackville, daughter of John Sackville, 3rd Duke of Dorset. He was the elder brother of Major-General Charles Sackville-West, 6th Earl De La Warr, Mortimer Sackville-West, 1st Baron Sackville, Lionel Sackville-West, 2nd Baron Sackville and Elizabeth Russell, Duchess of Bedford. He was educated at Christ Church, Oxford.[1]
Lord Cantelupe served in the Grenadier Guards, reaching the rank of lieutenant.[1] In 1837 he was returned to Parliament for Helston, a seat he held until 1840,[1] and then represented Lewes until 1841.[1] He died unmarried in June 1850, aged 36, predeceasing his father. His younger brother Charles eventually succeeded in the earldom.[1]
