Duke of Sutherland is a title in the Peerage of the United Kingdom which was created by William IV in 1833 for George Leveson-Gower, 2nd Marquess of Stafford. A series of marriages to heiresses by members of the Leveson-Gower family made the dukes of Sutherland one of the richest landowning families in the United Kingdom. The title remained in the Leveson-Gower family until the death of the 5th Duke of Sutherland in 1963, when it passed to the 5th Earl of Ellesmere from the Egerton family.

George Granville Leveson-Gower, 1st Duke of Sutherland KG, PC, known as Viscount Trentham from 1758 to 1786, as Earl Gower from 1786 to 1803 and as the Marquess of Stafford from 1803 to 1833, was an English politician, diplomat, landowner and patron of the arts from the Leveson-Gower family. He was the wealthiest man in Britain during the latter part of his life. He remains a controversial figure for his role in the Highland Clearances.
