苏格兰事务大臣（Secretary of State for Scotland）是英国政府在大不列颠和北爱尔兰联合王国苏格兰代表主要大臣。他所领导的苏格兰政府部门总部设在伦敦和爱丁堡。

在1999年的苏格兰分权，意味苏格兰事务大臣的权力被划分，大部分转移到苏格兰政府或其他英国政府部门。因此苏格兰事务大臣为苏格兰的作用被削弱。目前苏格兰事务大臣是戴维·蒙戴尔（David Mundell）。

Her Majesty's Principal Secretary of State for Scotland (Scottish Gaelic:Rùnaire Stàite na h-Alba, Scots:Secretar o 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.
