Deothang (also spelt 'Dewathang') is in Samdrup Jongkhar District in eastern Bhutan.
The main bazaar in the village is one long tree lined street, giving the village an appearance more similar to an Indian hill station than a traditional Bhutanese settlement. The entrance to the village is dominated by army barracks of the Royal Bhutan Army, while on the hill beyond the town is a technical college, a large hospital and Deothang Middle Secondary School. Due to the large population of army families and students, the village is relatively prosperous and enjoys a more pleasant climate than Sandrup Jongkhar 18 kilometers down the mountain on the plains. On a hill overlooking the village is the Chyoki Gyatso Institute of Buddhist Studies - a college in the Nyingma tradition of Buddhism founded by Dzongsar Khyentse Rinpoche - the famous director of the movies 'The Cup' and Travellers and Magicians.
During the Duar War (1864-65), the town, which was known at the time as Dewangiri, was taken by the British and a small garrison was based there. The Bhutanese regained control in 1865.
Deothang is on the main Trashigang to Samdrup Jongkhar highway.
There are a number of small guesthouses in the town.
