Jinniushan (Chinese: 金牛山) is a Middle Pleistocene paleoanthropological site, dating to around 260,000 BP, most famous for its archaic hominin fossils. The site is located near Yingkou, Liaoning, China. Several new species of extinct birds were also discovered at the site.

The hominid fossils at Jinniushan all belong to one individual. Initially, the fossils were believed to have belonged to a male specimen, since the fossils were so big. Later analysis shows that the fossil remains actually come from a female specimen.
