'''''Bos''''' (dari [[bahasa Latin]] ''bōs: [[lembu]]'') merupakan [[genus]] bagi lembu bela jinak mahupun liar. ''Bos'' boleh terbahagi kepada empat [[subgenus]]: ''Bos'', ''Bibos'', ''Novibos'', dan ''Poephagus'', tetapi boleh dipertikaikan. Genus ini mempunyai lima spesies yang [[Takson ekstan|masih wujud]]. Tetapi ini mungkin meningkat jadi tujuh jika varian [[bela jinak]] dikira spesies berasingan, dan sembilan jika genus rapat ''[[Bison]]'' turut disertakan.<ref>Groves, C. P., 1981.
