The Rajneesh movement is a religious movement inspired by the Indian mystic Bhagwan Shree Rajneesh (1931–1990), also known as Osho. They used to be known as Rajneeshees or "Orange People" because of the orange they used from 1970 until 1985. Members of the movement are sometimes called Oshoites in the Indian press.

Rajneesh, also known as Acharya Rajneesh, Bhagwan Shree Rajneesh, and later as Osho, was an Indian godman, philosopher, mystic, and founder of the Rajneesh movement. He was viewed as a controversial new religious movement leader during his life. He rejected institutional religions, insisting that spiritual experience could not be organized into any one system of religious dogma. As a guru, he advocated meditation and taught a unique form called dynamic meditation. Rejecting traditional ascetic practices, he advocated that his followers live fully in the world but without attachment to it. In expressing a more progressive attitude to sexuality he caused controversy in India during the late 1960s and became known as "the sex guru".
