Aileen Fox, née Henderson (29 July 1907, London – 21 November 2005, Exeter) was an English archaeologist.
The daughter of a solicitor, she was educated at Downe House School in Kent and later at its new site in Berkshire, under the headship of Olive Willis, and went on to read English at Newnham College, Cambridge. Following her graduation in 1929, she worked as a volunteer on the excavation of Richborough. In 1933 she married Sir Cyril Fox (who was 25 years older than she was), and they had three sons. The Foxes excavated prehistoric and Roman sites throughout the UK. Her most notable achievement was her work on Roman Exeter. She also lectured at several universities in Britain and New Zealand. Following her husband's knighthood, she became known as Lady Fox.
