Siang district is an administrative district in the state of Arunachal Pradesh in north-eastern India. It is one of several districts named after the Siang River, the principal stream which becomes the Brahmaputra after it enters Assam. The district was carved out of the older East Siang and West Siang districts as part of a wider reorganisation of districts in Arunachal Pradesh.

Siang district lies in the central part of Arunachal Pradesh, in the hilly terrain drained by the Siang River and its tributaries. The landscape is characterised by steep ridges, narrow river valleys and dense subtropical and temperate forests typical of the eastern Himalayan foothills. The district shares boundaries with several other Siang-group districts, including East Siang, West Siang, Upper Siang and adjoining administrative units in central Arunachal Pradesh.
The district headquarters is at Boleng, a small town on the banks of the Siang. Administratively the district is divided into circles and sub-divisions headed by Circle Officers and Additional Deputy Commissioners, with a Deputy Commissioner heading the district administration. Law and order is overseen by a Superintendent of Police. The district falls within the jurisdiction of the Gauhati High Court's Itanagar Permanent Bench.
The population of Siang district is largely tribal, with the Adi community forming the dominant group. Several Adi sub-groups inhabit the area, and traditional institutions such as the kebang (village council) continue to play a role in community life. Major festivals observed in the district include Solung and Aran, which are agricultural and ritual festivals of the Adi people. Donyi-Polo, the indigenous animist faith centred on the Sun and the Moon, is widely followed alongside Christianity.
The economy is predominantly agrarian. Shifting cultivation (jhum) and settled wet-rice farming are practised, with maize, millet, paddy and vegetables among the principal crops. Horticulture, particularly oranges and other citrus fruits, contributes to household incomes. Forestry, small-scale handloom weaving and bamboo and cane crafts are traditional sources of livelihood. Government employment and small trade form the bulk of the non-agricultural economy.
The district is connected by state highways and district roads maintained by the Public Works Department and the Border Roads Organisation. Road links connect Boleng with Pasighat in East Siang and with Aalo in West Siang. The Siang River, though not extensively navigable in this stretch, has historically been an important corridor of movement and settlement.
The creation of Siang district was part of a policy of bringing administration closer to remote communities in Arunachal Pradesh by reducing the size and travel distances of older, larger districts. Its location along the central reach of the Siang River, near areas of strategic and ecological importance, gives it relevance in discussions on hydropower, river ecology and border-area development in the eastern Himalaya.
