''Bison gaurus'' was the [[scientific name]] proposed by [[Charles Hamilton Smith]] in 1827.<ref>{{cite book |editor1=Griffith, E. |year=1827 |title=The animal kingdom arranged in conformity with its organization |volume=5.

To date, three gaur [[subspecies]] have been recognized:
* ''B. g. gaurus''; the nominate subspecies, ranges in India, Nepal and Bhutan.<ref name="Ellerman66"/>
* ''B. g. readei''; described by [[Richard Lydekker]] in 1903, based on a specimen from [[Myanmar]], and is thought to range from [[Upper Myanmar]] to [[Tanintharyi Region]].<ref name=Lydekker1913>{{cite book |author=Lydekker, R. |year=1913 |title=Catalogue of the ungulate mammals in the British Museum (Natural History) |volume=1 |location=London |publisher=Trustees of the British Museum |chapter=''Bos gaurus readei'' |page=20 |chapter-url=https://archive.org/stream/catalogueofungul01britrich#page/20/mode/2up}}</ref>
* ''B. g. hubbacki''; described by Lydekker in 1907, based on a specimen from [[Pahang]] in [[Peninsular Malaysia]].<ref name=Lydekker1913/> It was thought to range from Peninsular Malaysia and northward through [[Tanintharyi Region|Tenasserim]]. This classification, based largely on differences in coloration and size, is no longer widely recognized.<ref>{{cite book |author1=Corbet, G. B. |author2=Hill, J.

In 2003, the [[International Commission on Zoological Nomenclature]] fixed the valid [[specific name (zoology)|specific name]] of the wild gaur as the first available name based on the wild population, despite being antedated by the name for the domestic form. Most authors have adopted the binomial ''Bos gaurus'' for the wild species as valid for the [[taxon]].<ref>{{cite journal |last1=Gentry |first1=A. |last2=Clutton-Brock |first2=J. |last3=Groves |first3=C.

In recognition of [[phenotypic]] differences between [[zoological specimen]]s of Indian and Southeast Asian gaur, the [[Trinominal nomenclature|trinomials]] ''Bos gaurus gaurus'' and ''Bos gaurus laosiensis'' are provisionally accepted, pending further [[morphometric]] and [[Genetics|genetic]] study.<ref name=iucn/>

Within the genus ''[[Bos]]'', the gaur is most closely related to the [[banteng]] (''Bos javanicus'') and the probably now extinct [[kouprey]] (''Bos sauveli''), which are also native to Southeast Asia.
