Ashim Chatterjee is an Indian politician and a former Naxalite leader. He was a student leader of Communist Party of India (Marxist-Leninist) (CPI(ML)) in Calcutta. Chatterjee broke ranks with Charu Majumdar in 1971 after the failure of the attempts to build an armed movement in the Debra-Gopiballavbur area in West Bengal and due to the opposition of CPI(ML) towards the liberation struggle of Bangladesh. He was imprisoned during 1972-78. Chatterjee formed the Bengal-Bihar-Odisha Border Regional Committee, CPI(ML) as a separate faction. His group joined the CPI(ML) of Satyanarayan Singh. Later Chatterjee formed the Communist Revolutionary League of India.
He unsuccessfully contested West Bengal legislative assembly (Bidhan Sabha) elections twice - first as a Communist Party of India (Marxist) (CPI(M)) supported Independent and in 2006, as a Trinamul Congress supported candidate. He is popularly called as comrade Kaka.
