Nora Kershaw Chadwick CBE FSA FBA (28 January 1891 – 24 April 1972)[1] was an English philologist who specialized in Anglo-Saxon, Celtic and Old Norse studies.

[2] She received her undergraduate degree from Newnham College, Cambridge (where she was later an Honorary Life Fellow) and lectured at St Andrews during World War I.

[4] Chadwick took an interdisciplinary approach and wrote on many topics; she demonstrated influentially the study of multiple "early cultures of north-west Europe" and brought comparative evidence to bear on heroic literature.

Chadwick collaborated with V. M. Zhirmunsky on a revision of the part of volume III that deals with epic poetry in Central Asian languages.

Chadwick wrote about Celtic Britain and Breton history, and collaborated with Myles Dillon and Kenneth H. Jackson.
