The All India Trinamool Congress (AITC), previously named West Bengal Trinamool Congress (WBTC), and more commonly referred to as simply the Trinamool Congress (TMC; transl. Grassroots Congress), is an Indian political party based in the state of West Bengal founded by Mamata Banerjee in 1998. AITC began as a breakaway faction of the Indian National Congress and rapidly rose to prominence in the politics of West Bengal under Banerjee's leadership. AITC ruled the state of West Bengal with Banerjee serving as Chief Minister from 2011 till 2026.

The party first came to rule the state after defeating the Left Front in 2011 elections. Subsequently, the party won in 2016 and 2021 elections. However, it failed to gain majority in 2026 election, and was defeated by the Bharatiya Janata Party (BJP).
