Nishada (niśāda) is the name of a kingdom mentioned in the Indian epic Mahabharata. The kingdom belonged to a tribe of the same name.
In the Mahabarata, Nishadas are mentioned as tribes that have the hills and the forests for their abode. They are linked with a king called Vena (See Saraswata Kingdom) who became a slave of wrath and malice, and became unrighteous. Brahmanas slew him. Some of Vena's descendants became Nishadas and some others were called Mlechchhas, who resided on the Vindhya mountains (12,58).
Ekalavya was a king of a Nishada tribe. He attacked Dwaraka once, and was killed by Vasudeva Krishna in the battle. This kingdom was located in Aravalli ranges in Rajasthan state of India, possibly the district named Bhilwara. Other than the kingdom of Ekalavya there were many other Nishada kingdoms.
