The word Rangaroon is derived from “Rai Gurung”, which is a Nepali caste. There is a substantial population of Rai and Gurung people in the little village and its neighboring area, giving rise to the name. It is also termed as Rangaroong and Rangeyroong. The region is a tea garden with the adjacent village - it is famous mainly for the Rangaroon tea garden. The Queen of the Hills, Darjeeling, is located only about 20 Kms from here.
