William Douglas, 9th Earl of Angus

William Douglas, 9th Earl of Angus (1533 – 1 July 1591, at Glenbervie) was a Scottish nobleman and zealous supporter of Mary, Queen of Scots.

Douglas was the eldest son of Sir Archibald Douglas of Glenbervie, Knt., by his spouse Agnes, daughter of William Keith, 3rd Earl Marischal, and upon the death of Archibald Douglas, 8th Earl of Angus without issue, William succeeded to that Earldom as heir-male, in 1588.

Sir Robert Douglas states that "Sir William Douglas of Glenbervie [as he was styled prior to his succession to the earldom] was a man of great honour and integrity, and a steady friend of Queen Mary. He accompanied her in her expedition to the north, and behaved with utmost fortitude and resolution at the fight of Corrichie anno 1562".

The earldom was claimed by James VI, who brought a suit against Douglas, for reducing the charters connected with the title, but on 7 March 1589, a decision was given in favour of the latter.

He had two charters under The Great Seal of Scotland, from Queen Mary, of the lands and barony of Glenbervie, Kemnay, and several others.

Douglas died in July 1591, in his 59th year.

The earl married Giles, daughter of Sir Robert Graham of Morphie, and had six sons and four daughters:
