Mary Mann Page Newton Stanard (1865 - June 5, 1929) was an American historian, specializing in the history of Virginia.
Born in Westmoreland County, Stanard was the daughter of John Brockenbrough Newton and Roberta Page (Williamson) Newton. She began her education in local schools before attending, and graduating from, the Leache-Wood School in Norfolk. On April 17, 1900, she married William Glover Stanard, at the time the corresponding secretary of the Virginia Historical Society, and with him took up residence in Richmond. Stanard's career as a historian began when she and her husband published The Colonial Virginia Register in 1902; in 1907 her first solo work, The Story of Bacon's Rebellion, appeared. She wrote and edited a number of books covering various aspects of Virginia history, and produced biographies of her father Bishop Newton, Edgar Allan Poe, and John Marshall. Until her death, Stanard was historian of the Association for the Preservation of Virginia Antiquities; she also served as vice-president of the state chapter of the Colonial Dames of America, and was a member of the executive committees of the Edgar Allan Poe Shrine and the Virginia War History Commission. She died in Richmond.
