Romney Sedgwick (1895 – 1972) was a British historian. He married Mana St David Hodson in 1936, having one son and one daughter together.
Eveline Cruickshanks wrote a book on the Tories and the Jacobite Rising of 1745 and said: "My greatest debt is to the late Romney Sedgwick, a staunch Whig, whose wit and erudition I greatly admired, for a series of discussions, heated at times, but, as I well know, much enjoyed on both sides".
