The Chaitanya Bhagavata (Bengali: চৈতন্য ভাগবত) is a hagiography of Chaitanya Mahaprabhu (b.1486), the Supreme Personality of Godhead Krishna incarnation in Kaliyuga, written by Vrindavana Dasa Thakura (1507-1589 CE). It was the first full-length work regarding Chaitanya Mahaprabhu written in Bengali language and documents his early life and role as the founder of the Gaudiya Vaishnava tradition. The text details Chaitanya's theological position as a combined Avatar of both Radha and Krishna within the belief of his close associates and followers. The writing of Chaitanya Bhagavata was commissioned by Nityananda, who was the guru of Vrindavana Dasa Thakura and close friend of Chaitanya Mahaprabhu.
Initially, the Chaitanya Bhagavata was named Chaitanya Mangala. Krishnadasa Kaviraja also mentioned this work by this name. According to the Premavilasa of Narottama Dasa, when it was discovered that the poet Lochana Dasa had also written a work with this title, the leading members of the Vaishnava community in Vrindavan met and decided that Vrindavana Dasa's book would be known as the Chaitanya Bhagavata with Lochana Dasa's book remaining as the Chaitanya Mangala.
The Chaitanya Bhagavata is divided into three parts: the Adi-khanda, Madhya-khanda and Antya-khanda:
The Adi-khanda consists of fifteen adhyayas (chapters). It deals with the socio-religious situation of Bengal before the advent of Chaitanya Mahaprabhu, his birth, education, and marriage to Lakshmi-priya; his defeating opposing scholars, his visit to East Bengal, the passing of Lakshmi-priya, his marriage to Vishnupriya and his trip to Gaya and subsequent initiation from Ishvara Puri.
