原牛（学名：Bos taurus primigenius），是一种已灭绝的牛亚种，是现代家牛未驯化的野生近亲。最后一只于1627年在波兰灭绝。原牛出现在欧洲和西亚的石器时代的洞穴壁画中，显示牠是重要的猎物。其英文名 Aurochs 和 Urus 起源于日耳曼语，意谓原始牛。^[1]^[2]^[3]^[4]^[5]^[6]

驯养及绝种

约公元前6000年，高加索南部及美索不达米亚北部开始驯养原牛，遗传证据显示北非及印度亦有另行驯化原牛^[7]^[8]，此一过程令原牛大为改变，甚至与现今的家牛变成另一亚种。

不过，今日欧洲的牛只是否起源自原牛的驯化过程，尚成疑问。虽然原牛早于铜器时代已从英国绝种，但遗传研究却发现当时的原牛与今日的牛种并无明显关连，有说认为欧洲家牛是直接由近东一带的原牛产生的后代。

最后一只原牛活动在波兰西部森林中，于1627年死于自然因素，最后一只原牛的死亡宣告了这一物种野生种群的灭绝。
