Lieutenant-General Richard Lumley, 1st Earl of Scarbrough (c. 1650 – 17 December 1721) was an English Army officer and Whig politician best known for his role in the Glorious Revolution.

Richard became the 2nd Viscount Lumley (in the Irish peerage) on his grandfather's death in 1661/1662, his father having died in 1658.

[3] Lumley attended the Duke of York on his way to Scotland in November 1679 and was a volunteer in the abortive expedition to Tangier in 1680.

He played a prominent part in the suppression of the rebellion of the Duke of Monmouth, having been personally responsible (according to John Evelyn) at the head of the Sussex Militia for Monmouth's arrest, unarmed and bearded in a dry ditch covered with fern brakes.

Lumley was one of the Immortal Seven, the English noblemen who invited William of Orange to invade England and depose his father-in-law, James II.
