Alice Mary Hadfield (14 December 1908 – 28 August 1989), born Alice Mary Smyth, was a British book editor and writer, the co-ordinating editor of the first edition of The Oxford Dictionary of Quotations (1941), and the librarian at Oxford University Press's Amen House.

They were both influenced by the ideas on Romantic Theology developed by Charles Williams who Alice Mary had met when he had been a member of the original committee on the contents of The Oxford Dictionary of Quotations, and they practiced in their marriage his theories of Co-inherence and the Way of Exchange.

[2] Hadfield replaced Phyllis Jones as librarian at Amen House for Oxford University Press.

She wrote on a diverse range of subjects that included British and local history, particularly of her native Cotswolds, produced a number of works with her husband, who was an expert on British canals, and wrote a children's series known as "The Williver chronicles".

She produced an adaption of Sir Thomas Malory's Le morte d'Arthur and a scholarly study of The Chartist Land Company.
