Commandur Rajagopalachari Rangachari better known as C.R. Rangachari, an Indian Cricketer of British colonial rule, was born on 14th April 1916, in Mammandur District. He was a fast bowler who represented India in Test cricket in colonial times. He played the domestic matches for Madras Cricket Team.

C.R. Rangachari was a medium pace bowler who bowled with a slight round-arm action and moved the ball away from the batsman.

C.R. Rangachari was a student of the Pachaiyappa`s College in Madras. When the Madras cricket league was started in 1932, C.R. Rangachari played for Chepauk United Club and then he switched to Triplicane CC, a domestic cricket club in South India. There, C.R. Rangachari formed a fearsome partnership with M.J. Gopalan. Rangachari first claimed the spotlight when he took 9 for 45 against Mysore in an inter-association junior match in 1938. The same year he was selected to the Ranji team.

C.R. Rangachari was also a fine fielder, and fielding usually at silly mid-off, formed a nice combination with the spinner A.G. Ram Singh. He was selected for the tour of Australia in 1947 to 1948. He took a hat-trick in the match against Tasmania. On his debut at Adelaide he took 4 for 141, dismissing Neil Harvey, Keith Miller, Ray Lindwall and Ian Johnson.
