Margaret Alice Murray FSA Scot FRAI (13 July 1863 – 13 November 1963) was a British Egyptologist, archaeologist, anthropologist, historian, and folklorist. The first woman to be appointed as a lecturer in archaeology in the United Kingdom, she worked at University College London (UCL) from 1898 to 1935. She was president of the Folklore Society from 1953 to 1955, and published widely.

Born to a wealthy middle-class English family in Calcutta, British India, Murray divided her youth between India, Britain, and Germany, training as both a nurse and a social worker. Moving to London, in 1894 she began studying Egyptology at UCL, developing a friendship with department head Flinders Petrie, who encouraged her early academic publications and appointed her junior lecturer in 1898. In 1902–1903, she took part in Petrie's excavations at Abydos, Egypt, there discovering the Osireion temple, and the following season investigated the Saqqara cemetery, both of which established her reputation in Egyptology. Supplementing her UCL wage by giving public classes and lectures at the British Museum and Manchester Museum, it was at the latter in 1908 that she led the unwrapping of Khnum-nakht, one of the mummies recovered from the Tomb of two Brothers – the first time that a woman had publicly unwrapped a mummy. Recognising that British Egyptomania reflected the existence of widespread public interest in Ancient Egypt, Murray wrote several books on Egyptology targeted at a general audience.

Murray became closely involved in the first-wave feminist movement, joining the Women's Social and Political Union and devoting much time to improving women's status at UCL. Unable to return to Egypt due to the First World War, she focused her research on the witch-cult hypothesis, the theory that the witch trials of Early Modern Christendom were an attempt to extinguish a surviving pre-Christian, pagan religion devoted to a Horned God. Although later academically discredited, the theory gained widespread attention and proved a significant influence on the emerging new religious movement of Wicca. From 1921 to 1931, she undertook excavations of prehistoric sites on Malta and Menorca and developed her interest in folkloristics. Awarded an honorary doctorate in 1927, she was appointed assistant professor in 1928 and retired from UCL in 1935. That year she visited The British mandate of Palestine (modern day Israel , Jordan and the Palestinian territories) to aid Petrie's excavation of Tall al-Ajjul and in 1937 she led a small excavation at Petra, Jordan. Taking on the presidency of the Folklore Society in later life, she lectured at such institutions as the University of Cambridge and City Literary Institute, and continued to publish until her death.

Murray's work in Egyptology and archaeology was widely acclaimed and earned her the nickname of "The Grand Old Woman of Egyptology", although after her death many of her contributions to the field were overshadowed by those of Petrie. Conversely, Murray's work in folkloristics and the history of witchcraft has been academically discredited and her methods in these areas heavily criticised. The influence of her witch-cult theory in both religion and literature has been examined by scholars, and she herself has been dubbed the "Grandmother of Wicca".

Margaret Murray was born on 13 July 1863 in Calcutta, then a major military city and the capital of British India. She lived in the city with her parents James and Margaret Murray, an older sister named Mary, and her paternal grandmother and great-grandmother. James Murray, born in India of Anglo-Irish descent, was a businessman and manager of the Serampore paper mills who was thrice elected President of the Calcutta Chamber of Commerce. Margaret (née Carr) had moved to India from Britain in 1857 to work as a missionary, preaching Christianity and educating Indian women. She continued with this work after marrying James and giving birth to her two daughters.

Although most of their lives were spent in the European area of Calcutta, which was walled off from the Indian sectors of the city, Murray encountered members of Indian society through her family's employment of ten Indian servants and through childhood holidays to Mussoorie. The historian Amara Thornton has suggested that Murray's Indian childhood exerted an influence over her throughout her life, expressing the view that Murray could be seen as having a hybrid transnational identity that was both British and Indian. During her childhood, Murray received no formal education, and in later life expressed pride that she had never had to sit an exam before entering university.

In 1870, Margaret and her sister Mary were sent to Britain, moving in with their uncle John, a vicar, and his wife Harriet at their home in Lambourn, Berkshire. Although John provided them with a strongly Christian education and a belief in the inferiority of women, both of which she would reject, he awakened Murray's interest in archaeology through taking her to see local monuments. In 1873, the girls' mother arrived in Europe and took them with her to Bonn in Germany, where they both became fluent in German. In 1875 they returned to Calcutta, staying there until 1877. They then moved with their parents back to England, where they settled in Sydenham, London. There, they spent much time visiting The Crystal Palace, while their father worked at his firm's London office.

In 1880, they returned to Calcutta, where Margaret remained for the next seven years. She became a nurse at the Calcutta General Hospital, which was run by the Sisters of the Anglican Sisterhood of Clower, and there was involved with the hospital's attempts to deal with a cholera outbreak. In 1881, at age 18, Margaret heard about James Murray (no relation) and his "general appeal to English speakers around the world to read their local books and send him words and quotations" for entry into the OED. She had a routine of taking a book onto the roof in the cool early-morning air. She began with William L'Isle's edition of Aelfric's Saxon Treatise concerning the Old and New Testament, from which she submitted 300 entries to Murray. She continued as a volunteer until 1888, submitting a total of 5,000 entries.
