Nanda or Nandagopa is a cow-herd chief, and the foster-father of Krishna, featured in the Harivamsha and the Puranas. Nanda is the son of Parjanya, a ruler of the Vraja region, who is a son of Devamidha. He is the chief of Gokulam, which was one of the mandals of the yadava tribe. He is sometimes referred to as a king but was a cow-herder in real.
Nanda was a brother of Vasudeva. Vasudeva takes his newborn son, Krishna, to Nanda on the night of the child's birth, so that Nanda could raise him and to protect new born Krishna from his maternal uncle Kamsa. The chief, who is married to Yashoda, brings up both Krishna, and his brother, Balarama. Krishna derives his epithet Nandanandana (son of Nanda) from him.
