Advaita Acharya (Bengali: অদ্বৈত আচার্য) (1434–1539), was a revered contemporary of Sri Chaitanya Mahaprabhu, during the Renaissance of Devotion, in medieval India. He is accepted as the fifth member of the sacred Pancha Tattva - also entitled as the Five Features of the Absolute Truth. Being an incarnation of Maha Vishnu, He is seen to be an eternal companion or nitya-parshad of Sri Krishna Chaitanya, the Golden Avatara. This is why He is highly honoured in the Gaudiya Vaishnava sampradaya, as a notable disciple and companion of the founder of the Gaudiya Vaishnava lineage, Chaitanya Mahaprabhu, and guru of Haridasa Thakur.Cite error: A <ref>

The ancestry and life of Advaita Acharya are narrated in a number of hagiographical works, which include the Balyalilasutra (1487?) of Krishnadasa in Sanskrit and the Advaitasutrakadacha of Krishnadasa, the Advaitamangala of Haricharanadasa, the Advaitaprakasha of Ishana Nagara and the Advaitavilasa of Naraharidasa in Bengali. Many of his activities are described in the Chaitanya Charitamrta, the Chaitanya Mangala and the Chaitanya Bhagavata.
