Beryl Smalley FBA (1905–1984) was an English historian best known for her work The Study of the Bible in the Middle Ages, originally published in 1941, but revised many times, a book that laid the foundations of modern study of the medieval popular Bible.

Later, she was a temporary assistant in Western manuscripts at the Bodleian Library, Oxford, and, in 1944, became tutor in history at St Hilda's College.

One of her more notable pupils was the internationally respected historian on mid-Tudor England, Jennifer Loach, a tutorial fellow at Somerville College, Oxford.

Smalley discovered the lost biblical lectures of John Wycliffe, though she had no sympathy for the man himself.

Smalley 'was not in the least convivial, but she cared greatly about people in an austere way and would take endless trouble over their minor needs—major ones were their own affair.'

"In 1929 she had been received into the Roman Catholic Church, and about ten or twelve years later had become a member of the Communist Party.
