Brigadier-General William Douglas (1688[1]–1747), of Kirkness, Kinross, was a British Army officer and politician who sat in the House of Commons from 1715 to 1722.

[2] First commissioned in 1709, Captain Douglas joined Croft's Light Dragoons from which, in 1720, he was appointed to the Coldstream Guards.

They were employed in Scotland on the dispersal of the clans, remaining there but a short time, as they could ill be spared from Flanders.

On 11 June 1737, Douglas married Anne, third daughter of Charles Howard, M.P., 3rd Earl of Carlisle, as her second husband, at St. George's, Hanover Square, contrary to the wishes of her relatives.

She was appointed in 1736 a Lady of the Bedchamber to the Princess of Wales (mother of George III), and for the rest of her life was a prominent figure at Court.
