Sir Humphrey Stafford,(c. 1341 – 31 October 1413), of Southwick, Wiltshire; Hooke, Dorset; and Bramshall, Staffordshire, was a member of the fifteenth-century English gentry. He held royal offices firstly in the county of his birth, and later in the west country, particularly Devon and Dorset, and has been called 'one of the wealthiest commoners in England' of the period.
