Niladevi

Niladevi (Sanskrit: नीलदेवी, romanized: Nīladevī, lit. 'blue goddess'), also rendered as Neela Devi or Nappinnai, is a Hindu goddess, and a consort of the preserver deity Vishnu, along with Sridevi and Bhudevi. Niladevi is primarily revered in South India, particularly in Tamil culture, as one of Vishnu's consorts. In Sri Vaishnava tradition, all three consorts of Vishnu are regarded as aspects of Mahalakshmi.

In Vishnu's avatar as Krishna, Niladevi is either regarded as Nagnajiti, the consort of Krishna in Dvārakā or in some accounts, as southern counterpart of Radha, the gopi consort of Krishna in North Indian traditions.
