Āpomūrti (Apomurti) was one of the sons born of the womb of Anasūya (Anasuya), sired by Maharṣi(Maharshi; Great Sage) Atri. He is also one of the five Ātreyas(Atreya, son of Atri) born during the Svāyambhuva (Swaymbhuba) Manvantara.

According to Vāyupurāṇa (Vayupurana) and Brahmāṇdapurāṇa (Brahmandapurana), during the second Manvantara in future, when Dharmasāvarṇi would be Manu, Apomūrti, then would be one of the Saptarṣi (Saptarshi; seven sages).

As per Mārkaṇdeyapurāṇa (Markandeyapurana), Āpomūrti would be one of the seven sages in Tritiya (Third) Sāvarṇi (Savarni) Manvantara.
