Dattatreya (Sanskrit: दत्तात्रेय, Dattātreya) or Datta is considered by Hindus to be god who is an incarnation of the Divine Trinity Brahma, Vishnu and Shiva. The word Datta means "Given", Datta is called so because the divine trinity have "given" themselves in the form of a son to the sage couple Atri and Anasuya. He is the son of Atri, hence the name "Atreya."

In the Nath tradition, Dattatreya is recognized as an Avatar or incarnation of the Lord Shiva and as the Adi-Guru (First Teacher) of the Adinath Sampradaya of the Nathas. Although Dattatreya was at first a "Lord of Yoga" exhibiting distinctly Tantric traits, he was adapted and assimilated into the more devotional (Sanskrit: bhakti) Vaishnavite cults; while still worshiped by millions of Hindus, he is approached more as a benevolent god than as a teacher of the highest essence of Indian thought. Dattatreya is credited as the author of the Tripura Rahasya given to Parasurama, a treatise on Advaita Vedanta.
