Dharan is a sub-metropolitan city in Sunsari District of Koshi Province, Nepal, which was established as a fourth municipality in the Kingdom in 1958. It is the third most populous city in Eastern Nepal after Biratnagar and Itahari. The Nepali word "dharan" means a saw pit. The rainforest from which the tree trunks came is still just on the edge of the city.
Much later the British Gurkha camp opened in October 1960. The use of the camp by British Gurkhas finished in the mid 1990s. Dharan has an estimated city population of 173,096 living in 34,834 households as per the 2021 Nepal census.
