C. T. Krishnamachari (5 June 1909 – 5 January 1993) was Head of the Department of Philosophy at Madras Christian College from 1958 to 1969 and the most prominent among contemporary Indian philosophers who paid close attention to psi phenomena.

Chari published extensively on extremely diverse topics, such as logic, linguistics, information theory, mathematics, quantum physics, philosophy of mind, and, of course, psi research.

His supervisor was Professor Parthasarathy (Major) and in 1953, his thesis was sent to a board of three judges that included Sir Karl Popper at University of London.

From then to his retirement in 1969, he and his family lived at Staff Bungalow 15 (behind Bishop Heber Hall) on the Madras Christian College Campus at Tambaram.

He had a long and engaged battle[10][11][12] of wits with Ian Stevenson who studied reincarnation[13] across South East Asia and published a lot of cases favoring the phenomenon.
