The Pazyryk burials are a number of Iron Age tombs found in the Pazyryk Valley of the Ukok plateau in the Altai Mountains, Siberia, south of the modern city of Novosibirsk. The tombs are Scythian kurgans, that is barrow-like tomb mounds of larch logs covered over by large cairns of boulders and stones, dated to between the 6th and 3rd centuries BCE. The Pazyryk kurgans are the type site of the wider Pazyryk culture. The site is included in the Golden Mountains of Altai UNESCO World Heritage Site.
