James Hamilton, 6th Earl of Abercorn, PC (Ire) (c. 1661 – 1734), was a Scottish and Irish peer and politician. Appointed a groom of the bedchamber to Charles II after his father's death in battle, he took the Williamite side at the Glorious Revolution and in March 1689 supplied Derry with stores that enabled the town to sustain the Siege of Derry until it was relieved in August. Shortly after inheriting a Scottish and Irish peerage from a second cousin, he was created a viscount in Ireland for his services to the Williamite cause.
