The Welsh Office () was a department in the Government of the United Kingdom with responsibilities for Wales. It was established in April 1965 to execute government policy in Wales, and was headed by the Secretary of State for Wales, a post which had been created in October 1964. It was disbanded on 1 July 1999 when most of its powers were transferred to the National Assembly for Wales, with some powers transferred to the Office of the Secretary of State for Wales (), a department popularly known as the Wales Office. The Welsh Office took over the responsibilities related to housing, local government and town and country planning, etc. for Wales which had previously been the responsibilities of several other government departments. Its responsibilities included Monmouthshire, which for some purposes had earlier been considered by some to lie within England.

Legislation specific to Wales, such as the Sunday Closing (Wales) Act 1881 and the Welsh Intermediate Education Act 1889, began to be introduced in the late 19th century. Responsibility for Welsh education was given to the Welsh Department of the Board of Education in 1907, and the following year the Royal Commission on Ancient and Historical Monuments in Wales and Monmouthshire was established. The Welsh Board of Health was formed in 1919, and the Welsh Department of the Ministry of Agriculture and Fisheries in 1922. A Boundary Commission for Wales was set up under the House of Commons (Redistribution of Seats) Act 1944. A Council for Wales and Monmouthshire was established in 1949 to monitor the effects of government policy.
