George William Campbell, 6th Duke of Argyll GCH, PC (22 September 1768 – 22 October 1839), styled Earl of Campbell from 1768 to 1770 and Marquess of Lorne from 1770 to 1806, was a Scottish Whig politician and nobleman.

Argyll was the eldest son of John Campbell, 5th Duke of Argyll and his wife, Elizabeth Campbell, 1st Baroness Hamilton, daughter of Colonel John Gunning.

Argyll sat as Member of Parliament for St Germans from 1790 to 1796. In 1806 he succeeded his father in the dukedom and entered the House of Lords. He was Lord Keeper of the Great Seal of Scotland from 1827 to 1828 and again from 1830 and 1839. In 1833 he was sworn of the Privy Council and appointed Lord Steward of the Household in the Whig administration headed by Lord Grey, a position he retained when Lord Melbourne became prime minister in July 1834. The Whigs fell from power in November 1834 but returned to office already in April 1835, when Argyll once again became Lord Steward under Melbourne. He continued in the post until his death in 1839. Argyll was also Lord-Lieutenant of Argyllshire from 1799 to 1839.
