The Naobaogou Formation is a geological formation in the Daqing Mountains of China. It is likely of Lopingian (Late Permian) age. It consists of three rhythms of sediment, labelled members I-III primarily of purple siltstone, but each with a thick basal conglomerate bed. It is notable for its fossil content, producing one of the most diverse Late Permian vertebrate faunas outside Russia and South Africa.{{Cite journal|last1=Liu|first1=J.|last2=Bever|first2=G.S.|year=2018|editor-last=Angielczyk|editor-first=K.|title=The tetrapod fauna of the upper Permian Naobaogou Formation of China: a new species of Elginia (Parareptilia, Pareiasauria)|journal=Papers in Palaeontology|volume=4|issue=2|pages=197–209|doi=10.1002/spp2.1105|s2cid=135273110 }}
