Udasi is a religious, ascetic sadhu sect of Sikhism focused on the teachings of its founder, Sri Chand (1494-1643), son of Guru Nanak Dev, the founder and the first Guru of Sikhism.

Guru Hargobind sent his oldest son Baba Gurditta (father of Guru Har Rai) to be a disciple of Sri Chand. Baba Gurditta led Udasis on missions outside of the Punjab region to propagate Sikhism.

Udasi, comes from the root word udas which means detachment or renunciation. Unlike the Khalsa sect, they do not prohibit shaving or cutting one's hair. Accordingly, not all Udasi males have beards and long hair, as other Sikhs, belonging to the Khalsa, do. Udasi mahants have maintained accurate records of the chain of succession from Sri Chand.

Udasi scholars like Anand Ghan have written commentaries on portions of the Guru Granth Sahib, along with Janamsakhis and gur-bilas works.

During the 18th century, Udasis escaped persecution by the Mughal Empire, as they look different from Khalsa Sikh and Akalis, in whose absence they took care of Sikh places of worship and kept the teachings of Sikhism alive. This responsibility was with them for more than a century, and at one point in history (approximately 1849), there were more than 250 Udasi akharas in India.
