Kokrajhar Assembly constituency is one of the 126 constituencies in the Assam Legislative Assembly, created in the 2023 delimitation by merging the former Kokrajhar West and Kokrajhar East seats. It is a general (unreserved) constituency in Kokrajhar district, the headquarters of the Bodoland Territorial Council, and falls under the Kokrajhar Lok Sabha segment.
The main political parties in Assam include the Bharatiya Janata Party (BJP), Congress, Asom Gana Parishad (AGP), All India United Democratic Front (AIUDF), Bodoland People's Front (BPF), United People's Party Liberal (UPPL), and the Communist Party of India (Marxist) (CPM).
In the 2021 Assam Assembly elections, the two predecessor seats produced a split result between the Bodoland's two main political forces. Kokrajhar West was won by BPF's Rabiram Narzary, defeating UPPL's Manaranjan Brahma by 12,071 votes. Kokrajhar East was won by UPPL's Lawrence Islary, defeating BPF's Pramila Rani Brahma by 20,095 votes. The 2026 contest in the merged seat — with BJP fielding Sewli Mohilary and Congress fielding Manik Ch. Brahma — will be the first real test of whether voters in this BPF-UPPL battleground can be consolidated under a single Kokrajhar assembly seat.
The 2026 Assam Assembly elections will test Chief Minister Himanta Biswa Sarma's BJP-led government, which swept to power with a comfortable majority in 2021. With the opposition Congress-AIUDF combine seeking to consolidate anti-incumbency sentiment, every constituency will be a crucial battleground in deciding whether the state returns a second consecutive BJP government.
