Namsai district is an administrative district of the state of Arunachal Pradesh in north-east India. Located in the eastern foothills of the state, it was carved out as a separate district in 2014 and has its administrative headquarters at the town of Namsai. The district is notable for its large Tai Khamti and Singpho population and for being one of the centres of Theravada Buddhism in India.

Namsai lies in the plains and low foothills of eastern Arunachal Pradesh, bordered by the state of Assam to the south and by the districts of Lohit and Lower Dibang Valley. The terrain is comparatively flat for Arunachal Pradesh, drained by tributaries of the Brahmaputra, including the Lohit and Noa-Dihing rivers. The area is heavily forested in parts and supports paddy cultivation, tea gardens and orange orchards.
The population is ethnically diverse. The Tai Khamti and Singpho communities, who follow Theravada Buddhism, form a significant share of the inhabitants, alongside Mishmi groups, Adivasi tea-garden communities and settlers from neighbouring states. Assamese, Khamti and Hindi are widely used languages.
Namsai district was created on 14 July 2014 by bifurcating the earlier Lohit district, in line with the Government of Arunachal Pradesh's policy of forming smaller administrative units to improve service delivery in remote regions. The district is administered by a Deputy Commissioner based at Namsai town.
Administratively, the district is organised into sub-divisions and circles, with major towns including Namsai, Chongkham, Mahadevpur and Piyong. It sends representatives to the Arunachal Pradesh Legislative Assembly from constituencies such as Namsai and Chowkham.
Namsai is widely associated with the Golden Pagoda (Kongmu Kham), a prominent Theravada Buddhist monastery near Namsai town built in the Burmese architectural style. The monastery is a regional centre for Buddhist learning and pilgrimage. Festivals such as Sangken, the traditional new year celebration of the Khamti and Singpho communities, are observed across the district. Other community festivals include Khan Lang Toi and the harvest celebrations of the local tribes.
The economy of Namsai is largely agrarian. Wet rice cultivation is widespread on the plains, supported by tea plantations, horticulture (notably oranges and pineapples) and small-scale forestry. The district lies along important road links connecting the upper Assam plains to the eastern districts of Arunachal Pradesh, and the town of Namsai serves as a commercial node for surrounding rural areas.
Namsai is connected by road to Tinsukia and Dibrugarh in Assam and to other districts of Arunachal Pradesh through state highways. The nearest broad-gauge railhead is at Tinsukia, and the nearest airport with regular services is Dibrugarh's Mohanbari Airport in Assam.
