Gaudiya Vaishnavism (IAST: Gauḍīya Vaiṣṇavasampradāyaḥ), also known as Chaitanya Vaishnavism, is a Vaishnava Hindu religious movement inspired by Chaitanya Mahaprabhu (1486–1534) in India. "Gaudiya" refers to the Gaura or Gauḍa region of Bengal (present-day Malda district of West Bengal and Rajshahi district of Bangladesh), with Vaishnavism meaning "the worship of Vishnu". Specifically, it is part of Krishnaism–Krishna-centric Vaishnavite traditions.
Its theological basis is primarily that of the Bhagavad Gita and Bhagavata Purana (known within the tradition as the Srimad Bhagavatam), as interpreted by early followers of Chaitanya, such as Sanatana Goswami, Rupa Goswami, Jiva Goswami, Gopala Bhatta Goswami and others.
