Amvarīṣa (Amvarisha) is one of the Nāga(s) (Naga; Snake) belonging to the order of Nāga(s), mentioned in Mahābhārata (Mahabharata), though his name is not found in the chapter of describing snake-names, in Mahābhārata. However, in Vāyupurāṇa (Vayupurana), while mentioning the sons of Kadrū (Kadru), the name of Amvarīṣa has been referred to. When the great snake came out of the mouth of Valarāma (Valarama), and went towards the sea, he was welcomed by other renowned snakes like Karkoṭaka (Karkotaka), Vāsuki (Vasuki), Takṣaka (Takshaka) and so on. Amvarīṣa was also one of them.
