Tibetan Buddhism (Tibetan: བོད་བརྒྱུད་ནང་བསྟན།; Chinese: 藏传佛教) are Buddhist teachings from Tibet. It is part of Mahayana buddhism and is one of three main branches still practiced today. The other two are Han Buddhism and Theravada. It is most widely practiced around the Himalayas, Central Asia, and Siberia.
It includes all of the Buddhist teachings (or "three vehicles"). All traditions of Tibetan Buddhism practice the vows of moral discipline (Pratimoksha) of the hearer's vehicle (Shrāvakayāna); the vows of universal liberation and philosophy of the great vehicle (Mahāyāna); and the pledges and special methods of the secret mantra vehicle (Vajrayāna).
