Hugh Campbell (born c. 1666, died 20th November 1731) was the eldest son of James, 2nd Earl of Loudoun. He succeeded to the title in 1684. Lord Loudoun held several important official posts in Scotland; he was a Lord of Session, a member of the Scottish Privy Council, and a Commissioner of the Treasury. In 1704 he was a joint Secretary of State for Scotland, and a Commissioner for the Union. In 1707 Lord Loudoun was made a Knight of the Order of the Thistle, and shortly afterwards Keeper of the Great Seal of Scotland and a member of the English Privy Council. Lord Loudoun fought at Sheriffmuir in 1715. He was one of the Scottish representative peers in the House of Lords, and Lord Lieutenant of Ayrshire. The Earldom of Loudoun descends through the female line and has consequently belonged to various families; it has been held by representatives, among others, of the families of Rawdon, Campbell, and Hastings.
