Earl of Stamford was a title in the Peerage of England. It was created in 1628 for Henry Grey, 2nd Baron Grey of Groby. This Grey family descended through Lord John Grey, of Pirgo, Essex, younger son of Thomas Grey, 2nd Marquess of Dorset, and younger brother of Henry Grey, 1st Duke of Suffolk (father of Lady Jane Grey); Suffolk was executed for treason in 1554 forfeiting his titles (see the Duke of Suffolk for earlier history of the family).

Lord John Grey's son Sir Henry Grey was in 1603 raised to the Peerage of England as Baron Grey of Groby, in the County of Leicester. He was succeeded by his grandson, the second Baron. He was created Earl of Stamford in the Peerage of England in 1628. Lord Stamford later fought as a Parliamentarian in the Civil War. His eldest son Thomas Grey, Lord Grey of Groby, was a leading Parliamentarian in the Civil War. He was one of the judges at the trial of Charles I and one of the regicides who signed the King's death warrant. He predeceased his father and never succeeded to the earldom. Lord Stamford's daughter Lady Elizabeth Grey married George Booth, 1st Baron Delamer, and was the mother of Henry Booth, 1st Earl of Warrington. He was succeeded by his grandson, the second Earl, who was the only son of Lord Grey of Groby. Lord Stamford was a politician and served as Chancellor of the Duchy of Lancaster and as President of the Board of Trade. He was childless and on his death in 1720 the titles passed to his first cousin, the third Earl. He was the son of the Hon. John Grey, younger son of the first Earl.
