Baron Stafford, referring to the town of Stafford, is a title that has been created several times in the Peerage of England. In the 14th century, the barons of the first creation were made earls. Those of the fifth creation, in the 17th century, became first viscounts and then earls. Since 1913, the title has been held by the Fitzherbert family.

Humphrey Stafford, 1st Duke of Buckingham, 6th Earl of Stafford, 7th Baron Stafford, of Stafford Castle in Staffordshire, was an English nobleman and a military commander in the Hundred Years' War and the Wars of the Roses. Through his mother he had royal descent from King Edward III, his great-grandfather, and from his father, he inherited, at an early age, the earldom of Stafford. By his marriage to a daughter of Ralph, Earl of Westmorland, Humphrey was related to the powerful Neville family and to many of the leading aristocratic houses of the time. He joined the English campaign in France with King Henry V in 1420 and following Henry V's death two years later he became a councillor for the new king, the nine-month-old Henry VI. Stafford acted as a peacemaker during the partisan, factional politics of the 1430s, when Humphrey, Duke of Gloucester, vied with Cardinal Beaufort for political supremacy. Stafford also took part in the eventual arrest of Gloucester in 1447.
