The Baul are a group of mystic minstrels of mixed elements of Tantra, Sufism, Vaishnavism and Buddhism, from the Bengal region of the Indian subcontinent, comprising Bangladesh and the Indian states of West Bengal, Tripura and Assam’s Barak Valley. Bauls constitute both a syncretic religious sect and a musical tradition. Bauls are a very heterogeneous group, with many sects, but their membership mainly consists of Vaishnava Hindus and Sufi Muslims. They can often be identified by their distinctive clothes and musical instruments. Lalon Shah is regarded as the most celebrated Baul saint in history.

Although Bauls comprise only a small fraction of the Bengali population, their influence on the culture of Bengal is considerable. In 2005, the Baul tradition of Bangladesh was included in the list of Masterpieces of the Oral and Intangible Heritage of Humanity by UNESCO.
