Tripti Mitra had been acting in theatre since her teens. She first acted in her cousin Bijon Bhattacharya's play Agun (Fire) in 1943. After watching her stage performance in noted IPTA play, Nabanna (Harvest) based on Bengal famine of 1943, director Khwaja Ahmad Abbas took her to Bombay to act in Gana Natya Sangha’s film Dharti Ke Lal in 1943, partly based on the play.
