George Granville Sutherland-Leveson-Gower, 2nd Duke of Sutherland KG (8 August 1786 – 27 February 1861), styled Viscount Trentham until 1803, Earl Gower between 1803 and 1833 and Marquess of Stafford in 1833, was a British Whig MP and peer from the Leveson-Gower family.
Sutherland-Leveson-Gower was born at Portland Place, London, as the eldest son of George Leveson-Gower, 1st Duke of Sutherland and his wife Elizabeth Gordon, de jure Countess of Sutherland.
He was educated at Harrow School from 1798 to 1803, then entered Christ Church, Oxford, where he graduated B.A. in 1806 and M.A. in 1810. In 1841 he graduated D.C.L. at the same university.
His father died in 1833, only six months after being created Duke of Sutherland by William IV for his support for the Reform Act 1832, and so this new title devolved on his eldest son. His mother, who was 19th Countess of Sutherland in her own right, died in 1839, and so her ancient Scottish title passed to George, who also became 20th Earl of Sutherland. As a result, the two titles were united in the same person until 1963. It was the 2nd Duke who assumed the additional surname of Sutherland, so that his family name became Sutherland-Leveson-Gower.
Between 1806 and 1808, Earl Gower travelled in Prussia and Russia. During the Prussian campaign against Napoleon's French forces, he spent time at the Prussians' general headquarters.
