Badal Sircar, also known as Badal Sarkar, was an influential Indian dramatist and theatre director, most known for his anti-establishment plays during the Naxalite movement in the 1970s and taking theatre out of the proscenium and into public arena, when he transformed his own theatre company, Shatabdi as a third theatre group . He wrote more than fifty plays of which Evam Indrajit, Basi Khabar, and Saari Raat are well known literary pieces. A pioneering figure in street theatre as well as in experimental and contemporary Bengali theatre with his egalitarian "Third Theatre", he prolifically wrote scripts for his Aanganmanch (courtyard stage) performances, and remains one of the most translated Indian playwrights. Though his early comedies were popular, it was his angst-ridden Evam Indrajit (And Indrajit) that became a landmark play in Indian theatre.Today, his rise as a prominent playwright in 1960s is seen as the coming of age of Modern Indian playwriting in Bengali, just as Vijay Tendulkar did it in Marathi, Mohan Rakesh in Hindi, and Girish Karnad in Kannada.

He was awarded the Padma Shri in 1972, Sangeet Natak Akademi Award in 1968 and the Sangeet Natak Akademi Fellowship, the highest honour in the performing arts by Govt. of India, in 1997.
