The Pazyryk burials are a number of Scythian (Saka) Iron Age tombs found in the Pazyryk Valley and the Ukok plateau in the Altai Mountains, Siberia, south of the modern city of Novosibirsk, Russia; the site is close to the borders with China, Kazakhstan and Mongolia.

Numerous comparable burials have been found in neighbouring western Mongolia.

The tombs are Scythian-type kurgans, barrow-like tomb mounds containing wooden chambers covered over by large cairns of boulders and stones, dated to the 4th–3rd centuries BCE. The spectacular burials at Pazyryk are responsible for the introduction of the term kurgan, a Russian word, into general usage to describe these tombs. The region of the Pazyryk kurgans is considered the type site of the wider Pazyryk culture. The site is included in the Golden Mountains of Altai UNESCO World Heritage Site.

The bearers of the Pazyryk culture were horse-riding pastoral nomads of the steppe, and some may have accumulated great wealth through horse trading with merchants in Persia, India and China. This wealth is evident in the wide array of finds from the Pazyryk tombs, which include many rare examples of organic objects such as felt hangings, Chinese silk, the earliest known pile carpet, horses decked out in elaborate trappings, and wooden furniture and other household goods. These finds were preserved when water seeped into the tombs in antiquity and froze, encasing the burial goods in ice, which remained frozen in the permafrost until the time of their excavation.

Because of a freak climatic freeze, some of the Altai-Sayan burials, notably those of the 5th century BCE at Pazyryk and neighbouring sites, such as Katanda, Shibe, and Tuekta, were isolated from external climatic variations by a protective layer of ice that conserved the organic substances buried in them. Certain geometric designs and sun symbols, such as the circle and rosette, recur at Pazyryk but are completely outnumbered by animal motifs. Such specifically Scythian features as zoomorphic junctures, i.e. the addition of a part of one animal to the body of another, are rarer in the Altaic region than in southern Russia. The stag and its relatives, however, figure as prominently in Altai-Sayan as in Scythian art.

"At Pazyryk too are found bearded mascarons (masks) of well-defined Greco-Roman origin, which were doubtless inspired by the Hellenistic kingdoms of the Cimmerian Bosporus."

Rudenko initially assigned the neutral label Pazyryk culture for these nomads and dated them to the 5th century BCE; the dating has been revised for barrows 1-5 at Pazyryk, which are now considered to date to the 4th–3rd centuries BCE. The Pazyryk culture has since been connected to the Scythians whose similar tombs have been found across the steppes. The Siberian animal style tattooing is characteristic of the Scythians. The artifacts show that these ancient Altai nomads had cultural and trading links to Central Asia, China and the Near East. There is evidence that Pazyryk trade routes were vast and connected with large areas of Asia including India, perhaps Pazyryk merchants largely trading in high quality horses.

The first tomb at Pazyryk, barrow 1, was excavated by the archaeologist M. P. Griaznov in 1929; barrows 2–5 were excavated by Sergei Ivanovich Rudenko in 1947–1949. While many of the tombs had already been looted in earlier times, the excavators unearthed buried horses, and with them immaculately preserved cloth saddles, felt and woven rugs including the world's oldest pile carpet, a 3-metre-high four-wheel funeral chariot from the 5th century BCE and other splendid objects that had escaped the ravages of time. These finds are now exhibited at the Hermitage Museum in Saint Petersburg.
