Oscar Stig Wikander (27 August 1908 – 20 December 1983) was a Swedish Indologist, Iranologist and religious scientist.

[1] While still young, Wikander gained a reputation as a brilliant scholar with deep knowledge across a wide range of fields.

His PhD examined lexical evidence in Sanskrit and the Avestan language on the importance of young warrior bands among the Indo-Iranians.

Wikander's thesis was much influenced by the research of the Austrian philologist Otto Höfler, who taught German at Lund University from 1928 to 1934.

After World War II, Wikander served as a Red Cross delegate in Greece and Turkey.

[1] The works of Wikander are still of importance to modern students of religion, particularly because he was able to draw upon a diverse number of primary sources in Greek, Latin, Arabic, Indo-Iranian and other languages to build his arguments.
