Chabua-Lahowal Assembly constituency is one of the 126 constituencies in the Assam Legislative Assembly, created as a new seat in the 2023 delimitation exercise. It is located in Dibrugarh district in upper Assam, drawing from the Chabua and Lahowal blocks — an area historically associated with tea gardens, oil installations, and the legacy of the Ahom kingdom. The constituency falls under the Dibrugarh 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).
As a newly created constituency, Chabua-Lahowal does not carry forward a direct 2021 result. Adjacent Dibrugarh constituencies showed strong BJP dominance in 2021: Tingkhong was won by BJP's Bimal Borah with 62,675 votes (53 per cent share), and Naharkatia by BJP's Taranga Gogoi. In 2026, BJP fields Binod Hazarika while Congress fields Pranjal Ghatowar for this new upper Assam constituency.
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. Tea garden worker welfare, connectivity in the Chabua-Lahowal belt, and oil sector employment are expected to be defining issues.
