Ajoy Biswas is an Indian politician from Tripura, and former member of the Communist Party of India (Marxist) (CPI(M)).

[2] Biswas gradually moved to national politics and was elected as a member of the Indian Parliament's 7th and 8th Lok Sabha from 1980 to 1989.

Biswas played an important role in building the party organisation among the Bengalis of Tripura.

[18] In late 1980s Biswas became vocal against then Tripura's Chief Minister and CPI(M) president Nripen Chakraborty's style of leadership.

[22] This ideological difference widened and attracted a central stage of CPI(M) national and politbureau meetings,[23] eventually leading Biswas to quit the party and form Janganotantrik Morcha.
