The word "Rangiya" is believed to have been derived from the local term "Randiya".

According to local folklore, "Ran" means 'war' and "Diya" means 'to give', indicating that Rangiya was a place where a conflict or battle took place between the Boro people and Bhutanese communities.

In modern times, Rangiya is part of Kamrupi cultural region.
