Commandur Rajagopalachari Rangachari (14 April 1916 – 9 October 1993) was a fast bowler who represented India in Test cricket. Rangachari was a medium pace bowler who bowled with a slight round-arm action and moved the ball away from the batsman. He was a student of the Pachaiyappa's College in Madras. When the Madras cricket league was started in 1932, he played for Chepauk United Club and then switched to Triplicane CC. Here he formed a fearsome partnership with M.J. Gopalan. Rangachari worked in the police department and retired as the Deputy Superintendent. He died from a cardiac failure.
