William Gordon, 2nd Earl of Aberdeen (1679 – 30 March 1745), known between c. 1691 and 1720 as Lord Haddo, was a Scottish landowner and Tory politician who sat in the British House of Commons briefly from 1708 to 1709 when he was declared ineligible, being the eldest son of a Scottish peer. He showed some Jacobite sympathies, but took no part in the rebellions.
