Satyananda Giri, is the monastic name of Manamohan Mazumder, an Indian monk and a monastic disciple of Kriya Yoga guru Swami Sri Yukteswar Giri. He was a close childhood friend of, and brother-disciple to, Paramahansa Yogananda. In his later monastic life, he served as the leader of several yoga training institutions in east India.

Kriya Yoga is a yoga system which consists of a number of levels of pranayama, mantra, and mudra, intended to rapidly accelerate spiritual development and engender a profound state of tranquility and God-communion. It is described by its practitioners as an ancient yoga system revived in modern times by Lahiri Mahasaya, who claimed to be initiated by a guru, Mahavatar Babaji, circa 1861 in the Himalayas. Kriya Yoga was brought to international awareness by Paramahansa Yogananda's book Autobiography of a Yogi and through Yogananda's introductions of the practice to the West from 1920.
