Roger Flower or Flore (d. 1427) was an English politician, 12 times MP for Rutland and four times Speaker of the House of Commons. He was son of William Flower, sheriff of Rutland for 1383, by Elena his wife. He was returned to parliament as Knight of the Shire for the county of Rutland in 1396-7, again in 1399, 1402, 1404, and 1413-14. He was one of the feoffees of the Brigittine nunnery founded by Henry V at Syon in 1414. Still representing the county of Rutland, he was chosen speaker of the House of Commons four times in 1416, 1417, 1419, and 1422, something unprecedented except in the case of Thomas Chaucer. He was a lawyer with considerable private and public interests. In 1416 he was made chief steward of the Duchy of Lancaster estates north of the Trent. Besides his ancestral manor of Oakham in Rutland, he held estates in Leicestershire. He was appointed High Sheriff of Rutland for 1407 and 1412.
