Colonel James Hamilton (died 1673) was the son of an Irish army officer and became a courtier to Charles II after the Restoration. He appears in the Mémoires du Comte de Grammont, written by his brother Anthony. The king appointed him ranger of Hyde Park and a groom of his bedchamber. In 1673 Hamilton lost a leg in a sea-fight with the Dutch and died from the wound a few days later. In 1701 his eldest son succeeded a cousin as 6th Earl of Abercorn.
