Sir Richard Weston KB (1465–1541) was a courtier and diplomatist; Governor of Guernsey, Treasurer of Calais and Under-Treasurer of the Exchequer during the reign of King Henry VIII of England.
Richard Weston, son of Edmund Weston of Boston in Lincolnshire, (an adherent of Henry VII), was born about 1465–6. Sir William Weston (died 1540) was his brother. Immediately after his accession, on 22 May 1509, Henry VIII appointed Richard to several offices, including that of governor of Guernsey. In 1511 he served under Thomas, Lord Darcy, in the English contingent sent to assist King Ferdinand of Spain, in his campaign against the Moors. On his return Weston visited the court of Spain, and received considerable honour. He was knighted by Henry VIII in 1514, and from 1516 was in personal attendance on the king as Knight of the Body. On 3 January 1518 he was dubbed Knight of the Bath. Next year he was one of the four "sad and ancient knights" who were "put into the king's privy chamber". In 1520 he followed Henry to the Field of the Cloth of Gold. Next year he sat on the jury which tried and condemned Edward Stafford, 3rd Duke of Buckingham. The manor of Sutton was granted to him on the day of the Duke's execution (17 May 1521).
In 1523 Weston served under Charles Brandon, 1st Duke of Suffolk, in France; in 1525 he became Treasurer of Calais, and in 1528 under-treasurer of England. He also served as knight of the shire for Berkshire in 1529.
