Brigadier General Alfred Douglas Miller, (1 March 1864 − 5 December 1933) was a British Army officer.
Miller was the son of Lieutenant-Colonel James Miller (1829−1909), late 11th Hussars, of Shotover Park, Wheatley, Oxfordshire, JP, DL, High Sheriff of Oxfordshire in 1880, and Sarah Dorothy (d. 1911), daughter of Thomas Moore Evans. The Miller family were, in previous generations, merchants in Scotland, with James Miller's father, Alexander, coming to own Ashford Hall, Middlesex.[1] [2] [3]
Miller was commissioned a lieutenant in the 2nd Dragoons (Royal Scots Greys) on 7 February 1885, and promoted to the rank of captain on 28 June 1893. He was adjutant of the Royal Scots Greys from 1896 to 1900.[4] With the outbreak of the Second Boer War he was chief staff officer to Sir John French and, on 24 December 1901, he was appointed a Deputy-Assistant Adjutant-General on the staff in South Africa.

For his service in the war, Miller was mentioned in despatches (dated 8 April 1902) received the Distinguished Service Order (DSO) in the South Africa Honours list published on 26 June 1902, and was noted for future staff employment.
