Henry Grey, 6th Earl of Kent

Henry Grey, 6th Earl of Kent (1541 – 31 January 1615) was an English peer.

He was a son of Henry Grey (1520–1545) and Margaret St. John and grandson of Henry Grey, 4th Earl of Kent. He was a younger brother of Reginald Grey, 5th Earl of Kent and an older brother of Charles Grey, 7th Earl of Kent.

He served as Lord Lieutenant of Bedfordshire from 1586 to his death. In 1587 he was one of the official witnesses at the execution of Mary, Queen of Scots.

He was married to Mary Cotton, daughter of Sir George Cotton and Mary Onley. There were no known children from the marriage; he was thus succeeded by his younger brother, Charles.
