Earl of Sunderland is a title that has been created twice in thePeerage of England. The first creation came in 1627 in favour ofEmanuel Scrope, 11th Baron Scrope of Bolton. The earldom became extinct upon his death in 1630, while the barony became either extinct or dormant (seeBaron Scrope of Bolton for more information on this title). The second creation came in 1643 in favour of the Royalist soldierHenry Spencer, 3rd Baron Spencer of Wormleighton.

TheSpencer family descended fromSir John Spencer (d. 1522), who acquired theWormleighton estate inWarwickshire and theAlthorp estate inNorthamptonshire. His grandsonSir John Spencer (d. 1586) was aKnight of the Shire forNorthamptonshire. The latter's grandsonSir Robert Spencer representedBrackley in Parliament during the late 16th century. In 1603, Sir Robert was raised to the Peerage of England asBaron Spencer of Wormleighton. He was succeeded by his eldest surviving son, William, the second Baron. He had previously represented Northamptonshire in Parliament. His eldest son was the aforementioned third Baron. In July 1643, he was createdEarl of Sunderland in the Peerage of England, but he was killed at theBattle of Newbury in September of the same year. He was succeeded by his two-year-old only son, Robert, the second Earl. He later gained great distinction as a statesman and notably served four times asSecretary of State for the Southern Department.

His eldest surviving son, Charles, the third Earl, also gained prominence as a statesman. He wasLord-Lieutenant of Ireland,Lord Privy Seal, Secretary of State for both the Northern and Southern Departments,Lord President of the Council andFirst Lord of the Treasury. However, his political career was ruined by theSouth Sea Bubble of 1720. Lord Sunderland married (as his second wife)Lady Anne Churchill, second daughter of the distinguished soldierJohn Churchill, 1st Duke of Marlborough, andSarah Jennings. Thedukedom of Marlborough was allowed to descend to the Duke's daughters and their sons after a special Act of Parliament was passed in 1716.

The third Earl was succeeded by his eldest surviving son (by his second wife), Robert, the fourth Earl. He died unmarried in 1729 at the age of 27 and was succeeded by his younger brother, Charles, the fifth Earl. In 1733, he succeeded his maternal aunt,Henrietta Godolphin, 2nd Duchess of Marlborough, as third Duke of Marlborough. The barony of Spencer of Wormleighton and earldom of Sunderland have remained subsidiary titles of the dukedom ever since. Earl of Sunderland has been used as thecourtesy title of the Duke's eldest male-line grandson.

John Spencer, fourth son of the third Earl of Sunderland by his second wife, succeeded to the family estates in Northamptonshire in 1733 after his elder brother inherited the dukedom of Marlborough. His sonJohn was createdEarl Spencer in 1765.Robert Spencer, second son of the second Baron, had been created Viscount Teviot in 1685.
