The gaur (Bos gaurus; /ɡaʊər/) is a large bovine native to the Indian Subcontinent 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 gayal or mithun originated partly from the wild gaur and is most common in the border regions of Northeast India (Assam, Manipur, Nagaland) and Bangladesh with Myanmar and Yunnan, China.
