Lord William Robert Keith Douglas was a British politician and landowner. He was the fourth son of Sir William Douglas, 4th Baronet of Kelhead and younger brother of both Charles Douglas, 6th Marquess of Queensberry and John Douglas, 7th Marquess of Queensberry. He represented the Dumfries Burghs constituency between 1812 and 1832 and served, on a number of occasions, as one of the Lord Commissioners of the Admiralty. He owned sugar plantation estates in Tobago which had formerly belonged to Walter Irvine, whose daughter, Elizabeth, he married on 24 November 1824. They had three sons, the second of which, Walter, went on to continue the Douglases of Grangemuir. He employed the future missionary Catherine Grant as a governess until 1843.
