Sir James Sibbald David Scott, 3rd Baronet (1814–1885) of Dunninald Castle, Forfarshire, was a Scottish antiquarian and army officer.
Born on 14 June 1814, he was eldest son of Sir David Scott, 2nd Baronet of Egham; his mother was Caroline, daughter of Benjamin Grindall.
He was a fellow of the Society of Antiquaries of London, and a member of the Royal Archæological Institute.
[1] Scott's major work was The British Army: its Origin, Progress, and Equipment, illustrated.
It contains a sketch of the military and naval history of the island, and describes in some detail the Morant Bay rebellion of 1865.
