John Stuart, 3rd Earl of Bute, KG, PC (25 May 1713 – 10 March 1792) was a Scottish nobleman who served as Prime Minister of Great Britain (1762–1763) under George III. He was arguably the last important favourite in British politics. He was the first Prime Minister from Scotland following the Acts of Union in 1707.

A close relative of the Clan Campbell (his mother was a daughter of the 1st Duke of Argyll), Bute succeeded to the Earldom of Bute (named after the Isle of Bute) upon the death of his father, James Stuart, 2nd Earl of Bute, in 1723. He was brought up thereafter by his maternal uncles, the 2nd Duke of Argyll and Archibald Campbell, 3rd Duke of Argyll, 1st and only Earl of Ilay, Viscount and Earl of Hay. Bute studied at Eton College (1720–1728) and the University of Leiden, Netherlands (1728–1732), where he graduated with a degree in civil and public law. On 24 August 1736, he married Mary Wortley Montagu (daughter of Sir Edward and Lady Mary Wortley Montagu), bringing the large Wortley estates to his family. In 1737, due to the influence of his uncles, he was elected a Scottish representative peer, but he was not very active in the Lords and was not reelected in 1741. For the next several years he retired to his estates in Scotland to manage his affairs and indulge his interest in botany.
