Changlang is a census town and headquarters of the Changlang district in the Indian state of Arunachal Pradesh. It has become one of the major districts in the area owing to the presence of crude oil, coal and mineral resources other than tourism and hydro power.

However, anyone desiring to visit Changlang or any other place in Arunachal Pradesh will require a ‘Restricted Area Permit’ or ‘Inner Line Permit’ issued by the Resident Commissioner and Deputy Commissioners of Arunachal Pradesh for Indian citizens. Foreign tourists however need to approach the Ministry of Home Affairs, Government of India office at New Delhi in order to secure permission to visit Changlang. Dibrugarh Airport and Tinsukia Railway Station are the closest points after which bus transportation is required to reach Changlang. Ranglum Crashed Aircraft debris from World War II and Salt Water Springs are abundantly found in this area of Changlang.
Its native people includes Tangsa, Naga (Lungchang, Pangsha, Hawi etc.), Lisu, Nocte and Singpho among others.More than 50 dialects (languages) are spoken here. Among all the districts in Arunachal Pradesh, Changlang is unique for its cultures, traditions, and languages (dialects). Many dialects of Changlang district are believed to be endangered, and some dialects are already extinct. One of the many reasons for this is believed to be the influx of mainland India's Hindi language and culture into north India.
An "Inner line Permit" (ILP) was introduced by Indian government as one of many initiatives to protect fragile cultures, traditions and dialects of the North East people (excluding that of Assam) of India including Changlang. ILP was unsuccessfully challenged in Guwahati Court during 2008 by mainland India.
