Sir Arthur Wynne Morgan Bryant (18 February 1899 – 22 January 1985) was an English historian, columnist for "The Illustrated London News" and man of affairs. His books included studies of Samuel Pepys, accounts of English eighteenth- and nineteenth-century history, and a life of George V. Whilst his scholarly reputation has declined somewhat since his death, he continues to be read and to be the subject of detailed historical studies.
