The Secretary of State for the Northern Department was a position in the Cabinet of the government of United Kingdom up to 1782.
Before 1782, the responsibilities of the two Secretaries of State were not divided up in terms of area of authority, but rather geographically. The Secretary of State for the Northern Department, the more junior of the two, was responsible for Northern England, Scotland, and relations with the Protestant states of Northern Europe. The more senior Secretary of State for the Southern Department was responsible for Southern England, Wales, Ireland, the American colonies (until 1768), and relations with the Catholic and Muslim states of Europe.
During the 18th century, Secretaries of State for the Northern Department, if peers, were often Leaders of the House of Lords as well.
