John Allen Giles (1808–1884) was an English historian. He was primarily known as a scholar of Anglo-Saxon language and history. He revised Stevens' translation of the Anglo-Saxon Chronicle and Bede's Ecclesiastical History of the English People. He was a fellow at Corpus Christi College, Oxford.

The Ecclesiastical History of the English People, written by Bede in about AD 731, is a history of the Christian Churches in England, and of England generally; its main focus is on the conflict between the pre-Schism Roman Rite and Celtic Christianity. It was composed in Latin, and is believed to have been completed in 731 when Bede was approximately 59 years old. It is considered one of the most important original references on Anglo-Saxon history, and has played a key role in the development of an English national identity.
