Her Majesty's Principal Secretary of State for Scotland (, ) is the principal minister of Her Majesty's Government in the United Kingdom of Great Britain and Northern Ireland representing Scotland. He heads the Scotland Office (formerly the Scottish Office), a government department based in London and Edinburgh. The post was created soon after the Union of the Crowns, but was abolished in 1746, following the Jacobite rebellion. Scottish affairs thereafter were managed by the Lord Advocate until 1827, when responsibility passed to the Home Office.
