Vaḷḷi (Tamil: வள்ளி) ("Creeper, Sweet potato plant") is a Hindu goddess, and the second consort of the deity Murugan. An incarnation of the goddess Sundaravalli, daughter of Vishnu, Valli is born on earth as the daughter of a chieftain, leading a life of a huntress. Murugan, the god of war, eventually woos and weds her, according to Tamil folklore. Both of their legends originate from the mountain region also known as Kurunji in Tamilakam. Her sister, Amritavalli (Devasena), also succeeds in marrying Murugan as the adopted daughter of Indra, making them sister-wives.
