The gaur (Bos gaurus; /ɡaʊər/), also known as the Indian bison, is a bovine native to South Asia and Southeast Asia, and has been listed as Vulnerable on the IUCN Red List since 1986. The global population was estimated at a maximum of 21,000 mature individuals in 2016, with the majority of those existing in India. It is the largest species among the wild cattle and the Bovidae. The domesticated form of the gaur is called gayal (Bos frontalis) or mithun.
