Marquess of Tweeddale (sometimes spelled Tweedale) is a title of the Peerage of Scotland, created in 1694 for the 2nd Earl of Tweeddale. Lord Tweeddale holds the subsidiary titles of Earl of Tweeddale (created 1646), Earl of Gifford (1694), Viscount of Walden (1694), Lord Hay of Yester (1488), and Baron Tweeddale, of Yester in the County of Haddington (1881), all but the last in the Peerage of Scotland. As Baron Tweeddale in the Peerage of the United Kingdom, Lord Tweeddale sat between 1881 and 1963 in the House of Lords. The Marquess's eldest son uses Viscount Walden as a courtesy title.
Lord Tweeddale also holds the title of Hereditary Chamberlain of Dunfermline.
The heir presumptive is the present holder's brother Lord Alistair Hay (b. 1955), whose heir presumptive is his half-brother Lord Andrew Arthur George Hay (b. 1959), whose heir apparent is his son Angus David George Hay (b. 1991).
