Her Majesty's Principal Secretary of State for Wales (Welsh: Ysgrifennydd Gwladol Cymru) is the principal minister of Her Majesty's Government in the United Kingdom with responsibilities for Wales. They are a member of the cabinet and the head of the Wales Office. They are responsible for ensuring Welsh interests are taken into account by Her Majesty's Government, representing the government within Wales and overseeing the passing of legislation which is only for Wales. The current Secretary of State for Wales is Alun Cairns, following Stephen Crabb's appointment as Work and Pensions Secretary.

In the first half of the 20th century, a number of politicians had supported the creation of the post of Secretary of State for Wales as a step towards Home Rule for Wales. A post of Minister of Welsh Affairs was created in 1951 under the Home Secretary and was upgraded to Minister of State level in 1954.

The Labour Party proposed the creation of a Welsh Office run by a Secretary of State for Wales in their manifesto for the 1959 general election. When they came to power in 1964 this was soon put into effect.

The post of Secretary of State for Wales came into existence on 17 October 1964; the first incumbent was Jim Griffiths, MP for Llanelli. The position entailed responsibility for Wales, and expenditure on certain public services was delegated from Westminster. In April 1965 administration of Welsh affairs, which had previously been divided between a number of government departments, was united in a newly created Welsh Office with the Secretary of State for Wales at its head, and the Welsh Secretary became responsible for education and training, health, trade and industry, environment, transport and agriculture within Wales.
