Rastafari, sometimes called Rastafarianism, is a religion that developed in Jamaica during the 1930s. It is classified as both a new religious movement and a social movement by scholars of religion.

It was a religious movement among black Jamaicans that teaches the eventual redemption of black people and their return to Africa, employs the ritualistic use of marijuana, forbids the cutting of hair, and venerates Haile Selassie as a god.
