Tor Julius Efraim Andræ (Swedish: [ˈtuːr anˈdreː]; 9 July 1885 in Vena – 24 February 1947 in Linköping) was a Swedish scholar of comparative religion and bishop of Linköping from 1936.
Coming from a clerical family, Tor Andræ studied Theology at Uppsala University, where he completed his Ph.D. in 1917. He became professor of the History of Religions at the University College of Stockholm in 1927, and in Uppsala two years later. He was appointed bishop of Linköping in 1936 and was the same year briefly Minister for Ecclesiastical Affairs (an archaic title which in reality meant Minister of Education) in the short-lived cabinet of Axel Pehrsson-Bramstorp.
Andræ was a student of Nathan Söderblom, whom he succeeded as member of the Swedish Academy in 1932. As a historian of religion, his particular interest lay in the early history of Islam, particularly its Jewish and Christian origins, and in the psychology of religion, but he also combined these interests in the study of early Islamic mysticism.
In 1985, Annemarie Schimmel remarked that until then only one study had "tried specifically to depict Muhammad's role in Islamic piety. Even today Tor Andrae's Die person Muhammeds in lehre und glaube seiner Gemeinde (1918) remains the standard work in this area, unsuperseded by any other major study, though complemented by random remarks in numerous modern work on Sufism. It is, however, unfortunately too little known even among Islamicists."
