The Trinamool Congress (TMC; transl. Grassroots Congress), officially All India Trinamool Congress, is an Indian political party that is mainly influential in the state of West Bengal. It was founded by Mamata Banerjee on 1 January 1998 as a breakaway faction of the Indian National Congress and rapidly rose to prominence in the politics of West Bengal under her leadership. Presently, it is ruling the state of West Bengal beside being the third-largest party in India in terms of number of MPs just after the Bharatiya Janata Party and National Congress.

The party won a historic victory in the 2011 West Bengal Legislative Assembly election by ending the 34-year-long Left Front rule, world's longest democratically elected communist government. It has won a three-time majority in the West Bengal Legislative Assembly and has been the ruling party in West Bengal since 20 May 2011. AITC is led by Mamata Banerjee as the chairperson of the party.
