John Ramsay, 1st Earl of Holderness (c. 1580 – January 1626), known as Sir John Ramsay between 1600 and 1606, and as the Viscount of Haddington between 1606 and 1621, was an important Scottish aristocrat of the Jacobean era, best known in history as the first favourite of James I when he became king of England as well as Scotland in 1603. Around July 1624 Holderness married his second wife, Martha Cockayne, daughter of a Northamptonshire knight. She survived him; they had no children.
