Dr Sarvepalli Radhakrishnan, OM, FBA, (5 September 1888 – 17 April 1975), was an Indian philosopher and statesman.

Radhakrishnan was one of India's most acclaimed scholars of comparative religion and philosophy. He is considered through his efforts to have built a bridge between East and West by having shown the philosophical systems of each tradition to be comprehensible within the terms of the other. He wrote authoritative exegeses of India's religious and philosophical literature for the English speaking world. His academic appointments included the King George V Chair of Mental and Moral Science at the University of Calcutta (1921-?) and Spalding Professor of Eastern Religions and Ethics at Oxford University (1936-1952).

He was the first Vice President of India (1952-1962), and the second President of India (1962-1967). Among the many honours he received were a British knighthood (1931) and the Bharat Ratna (1954). His birthday is celebrated in India as Teacher's Day on 5 september
