Peking Man (Homo erectus pekinensis) is a subspecies of H. erectus which inhabited what is now northern China during the Middle Pleistocene. Its fossils have been found in a cave some 47 km (29 mi) southwest of Beijing (then referred to in the West as Peking), known as the Zhoukoudian Peking Man Site. The first fossil, a tooth, was discovered in 1921, and Zhoukoudian has since become the most productive H. erectus site in the world. Peking Man was instrumental in the foundation of Chinese anthropology, and fostered an important dialogue between Western and Eastern science. Peking Man became the centre of anthropological discussion, and was classified as a direct human ancestor, propping up the Out of Asia theory that humans evolved in Asia.

Peking Man also played a vital role in the restructuring of the Chinese identity following the Chinese Communist Revolution, and was intensively communicated to the general populace to introduce them to Marxism and science. Early models of Peking Man society strongly leaned towards communist or nationalist ideals, leading to discussions on primitive communism and polygenism. This produced a strong schism between Western and Eastern interpretations, especially as the West adopted the Out of Africa theory in the late 20th century, and Peking Man's role in human evolution diminished as merely an offshoot of the human line. Though Out of Africa is now the consensus, Peking Man interbreeding with human ancestors is discussed especially in Chinese circles.

Peking Man characterises the "classic" H. erectus anatomy. The skull is long and heavily fortified, featuring an inflated bar of bone circumscribing the crown, crossing along the brow ridge, over the ears, and connecting at the back of the skull, as well as a sagittal keel running across the midline. The bone of the skull and long bones is exorbitantly thickened. The face is protrusive (midfacial prognathism), the eye sockets are wide, the jaws are robust and chinless, the teeth are large, and the incisors are shovel-shaped. Brain volume ranged from 850 to 1,225 cc, for an average of just over 1,000 cc (within the range of variation for modern humans). The limbs are broadly anatomically comparable to those of modern humans. H. erectus in such northerly latitudes may have averaged roughly 150 cm (4 ft 11 in) in height, compared to 160 cm (5 ft 3 in) for more tropical populations.

Peking Man lived in a cool, predominantly steppe, partially forested environment, alongside deer, rhinos, elephants, bison, buffalo, bears, wolves, big cats, and other animals. Peking Man intermittently inhabited Zhoukoudian from potentially as far back as 800,000 years ago to as recent as 230,000 years ago, but the precise chronology is unclear. This spans several cold glacial and warm interglacial periods. The cultural complexity of Peking Man is fiercely debated. If Peking Man was capable of hunting (as opposed to predominantly scavenging), making clothes, and controlling fire, the population would have been well-equipped to survive frigid glacial periods. If not, the population would have had to retreat southward and return later. It is further disputed if Peking Man inhabited the cave, or was killed by giant hyenas (Pachycrocuta) and dumped there, in addition to other natural processes. Over 100,000 pieces of stone tools were recovered from Zhoukoudian, mainly wastage; but also many simple choppers and flakes, and a few retouched tools such as scrapers and possibly burins.
