Otto Max Helmuth von Glasenapp (8 September 1891 – 25 June 1963) was a German Indologist and religion scholar specialized as a historian of Indian philosophy, who taught as a professor at the University of Königsberg in East Prussia (1928–1944) and Tübingen (1946–1959).

Von Glasenapp travelled to India for the first time in 1927, and undertook numerous other study and lecture trips to various countries in Africa and the East over the following decades.

In 1928, von Glasenapp succeeded Rudolf Otto Franke [de] as Associate Professor of Indology at the Albertus University in Königsberg, a position he held until the end of the Second World War.

On 6 May 1946, he was given the chair of Indology and Comparative Religious Studies of his former teacher Richard Karl von Garbe in Tübingen, which had become vacant following the dismissal of Jakob Wilhelm Hauer.

In addition to numerous individual historical-philological studies on works of Sanskrit literature and German translations of Classical Sanskrit poetry, von Glasenapp published a series of comprehensive overviews of the three major Dhārmic religions (Hinduism, Jainism, and Buddhism) and their respective philosophies, some of which are still regarded as standard works today, have been reprinted numerous times in various languages and have also met with a wide reception in India.
