The secretary of state for Scotland (Scottish Gaelic: Rùnaire Stàite na h-Alba; Scots: Secretar o State fir Scotland), also referred to as the Scottish secretary, is a secretary of state in the Government of the United Kingdom, with responsibility for the Scotland Office. The incumbent is a member of the Cabinet of the United Kingdom. The Secretary of State for Scotland serves as the custodian of the Scottish devolution settlement as outlined in the Scotland Act 1998, and represent Scottish interests within the UK Government as well as advocate for UK Government policies in Scotland. The secretary of state for Scotland is additionally responsible for partnership between the UK Government and the Scottish Government, as well as relations between the Parliament of the United Kingdom and the Scottish Parliament.

Much of the secretary of state for Scotland's responsibility transferred to the office of the first minister of Scotland upon the establishment of a new Scottish Executive, since renamed the Scottish Government, and a new devolved Scottish Parliament in 1999 following the Scotland Act 1998.

The office holder works alongside the other Scotland Office ministers. The secretary of state for Scotland is supported by their deputy, the parliamentary under-secretary of state for Scotland. The incumbent is Douglas Alexander, following his appointment by Prime Minister Keir Starmer in September 2025. The corresponding shadow minister is the shadow secretary of state for Scotland.

The post was first created after the Acts of Union 1707 created the Kingdom of Great Britain from the Kingdom of England and the Kingdom of Scotland. It was abolished in 1746, following the Jacobite rising of 1745. Scottish affairs thereafter were managed by the lord advocate until 1827, when responsibility passed to the Home Office. In 1885 the post of secretary for Scotland was re-created, with the incumbent usually a member of the Cabinet. In 1926 this post was upgraded to a full secretary of state appointment.

After the 1999 Scottish devolution, the powers of the Scottish Office were divided, with most transferred to the Scottish Government or to other British government departments, leaving only a limited role for the Scotland Office. From June 2003 to October 2008, the holder of the office of secretary of state for Scotland also held another Cabinet post concurrently, leading to claims that the Scottish role was seen as a part-time ministry.

With the advent of legislative devolution for Scotland in 1999, the role of secretary of state for Scotland was diminished. Most of the functions vested in the office since administrative devolution in the 19th century were transferred to the newly established Scottish Ministers upon the opening of the Scottish Parliament, or to other UK government ministers. Most of the functions and powers of the secretary of state for Scotland transferred to the first minister of Scotland as the head of the Scottish Government. Donald Dewar served as the first first minister of Scotland between 1999–2000, having previously served as the secretary of state for Scotland between 1997–1999.

However, the secretary of state does represent Scotland in the Cabinet of the United Kingdom on matters that are not devolved to the Scottish Parliament, and also holds Scotland Questions on the first Wednesday of every month between 11:30 am and 12 noon, when any member of Parliament can ask a question on any matter relating to Scotland. However, devolved issues are not usually raised by MPs, as these are decided solely by Scottish Government policy, and influenced, discussed and voted on by members of the Scottish Parliament in Edinburgh. Moreover, the secretary of state for Scotland cannot introduce any bill or legislation in the UK Parliament relating to a devolved matter under the convention that the UK Government will not introduce legislation on devolved areas without the agreement of the Scottish Parliament. The secretary of state is also the group leader of the Scottish MPs from the government party.

The office mainly acts as a go-between for the UK and Scottish Governments and Parliaments. However, due to the secretary's position as a minister in the British government, the convention of Cabinet collective responsibility applies, and as such the post is usually viewed as being a partisan one to promote the UK government's decision-making in Scotland, as adherence to the convention precludes doing anything else.
