Sir Henry Erskine, 5th Baronet (23 Dec 1710 – 7 August 1765) was a Scottish soldier and politician.
He was a younger son of Sir John Erskine, 3rd Baronet, M.P. of Alva, Clackmannanshire, and Catherine Sinclair, was probably educated at Eton College and entered Lincoln's Inn to study law in 1728. However, instead of a legal career he joined the Army and rose to the rank of Lieutenant-General in 1765.[1]
He died in 1765. He had married Janet, the daughter of Peter Wedderburn, Lord Chesterhall, and with her had two sons and a daughter. He was succeeded by his eldest son James, who later became the 2nd Earl of Rosslyn.
