Reginald Lane Poole, FBA (1857–1939) was a British historian. He was Keeper of the Archives^[1] and a lecturer in diplomatics at the University of Oxford, where he gave the Ford Lectures in 1912 on the subject of "The Exchequer in the Twelfth Century".^[2][3] The second of three children (two sons and a daughter) of Edward Stanley Poole (1830–1867) and his wife, Roberta Elizabeth Louisa (1828–1866), daughter of Charles Reddelien, a naturalized German, the "Lane" in his surname comes from his paternal grandmother Sophia Lane Poole, author of An Englishwoman in Egypt (1844). Both his mother and father died during his childhood, so Poole and his siblings were raised by their grandmother Sophia Lane Poole and their great-uncle Edward William Lane. He was the father of Austin Lane Poole (1889–1963), also a historian and Ford's Lecturer; the brother of the orientalist Stanley Lane-Poole; and the nephew of Reginald Stuart Poole.^[4][5]

He edited, among other works, with W. Hunt, Political History of England (twelve volumes, 1905–10).^[6]

• History of the Huguenots of the Dispersion (1880)
