George Hay, 7th Marquess of Tweeddale DL (1753 – 9 August 1804) was a Scottish peer.
Hay was a great-grandson of the 2nd Marquess of Tweeddale, and in 1787 he inherited the titles of his first cousin once-removed, the 6th Marquess. He then became a Burgess of Edinburgh a year later, Lord Lieutenant of Haddingtonshire in 1794, and a Scottish representative peer in 1796. On 18 April 1785, he married Lady Hannah Maitland (a daughter of the 7th Earl of Lauderdale) and they had (with two other unmarried daughters):
- George, Earl of Gifford; later 8th Marquess of Tweeddale (1787–1876)
 - Lord James (1788–1862), army general, married Elizabeth Forbes
 - Lord John (1793–1851), rear-admiral, married Mary Cameron
 - Lord Edward George (1799–1862), colonel, died unmarried
 - Lord Thomas (1800–1890), religious minister, married Harriet Kinloch
 - Lady Julia Tomasina (178ì97;d. 1835), married John Hobhouse the 1st Baron Broughton
 - Ladu Elizabeth (d. 1868), married James Hope-Vere (a great-grandson of the 1st Earl of Hopetoun)
 - Lady Dorothea Frances (d. 1875), married John Ley
 - Lady Hannah Charlotte (d. 1876), married John Tharp (a grandson of the 4th Earl of Dunmore)
 
As a result of the marquess's declining health, he and his wife went to travel the Continent in 1802, starting in France. It was here that they were captured by Napoleon's police a year later, with other British subjects, when war was renewed between the two countries. They were then imprisoned in the fortress at Verdun and the marchioness died there on 8 May 1804, as did the marquess during the following August.
