Sir Arthur Wynne Morgan Bryant, CH, CBE (18 February 1899 – 22 January 1985), was a British historian and a columnist for the Illustrated London News. His books included studies of Samuel Pepys, accounts of English eighteenth- and nineteenth-century history, and a life of George V. Although his reputation has declined somewhat since his death, he continues to be read and to be the subject of detailed historical studies.
Bryant's historiography was based on an English romantic exceptionalism drawn from his nostalgia for an idealized agrarian past. He hated modern commercial and financial capitalism, he emphasized duty over rights, and he equated democracy with the consent of "fools" and "knaves".
Arthur Bryant was the son of Sir Francis Morgan Bryant, who was the chief clerk to the Prince of Wales, and wife May. His father would later hold a number of offices in the royal secretariat, eventually becoming registrar of the Royal Victorian Order. Arthur grew up in a house bordering the Buckingham Palace gardens near the Royal Mews. There he developed a feel for the trappings of traditional British protocol and a strong attachment to the history of England.
