Sir William Linton KCB (1801 – 9 October 1880) was a Scottish army physician.
After serving in Canada, the Mediterranean, and the West Indies, he was appointed deputy inspector-general of hospitals of the first division of the army in the Crimea, was present in every action up to the battle of Balaclava, and had care of the barrack hospital in Scutari shortly after its establishment in 1854 until the British forces came home.
In the following year he proceeded to India as inspector-general of hospitals, to which was soon added the post of principal medical officer of the European army.
His unremitting zeal was rewarded by his being in 1859 enrolled among her majesty's honorary physicians, and in 1865 he was advanced to the dignity of K.C.B.
Linton retired from the active list in 1863, and died unmarried at his residence of Skairfield, Lockerbie, Dumfriesshire, on 9 October 1880.
