The Dengying Formation is an upper Ediacaran (551-541 Ma[2]) fossiliferous geologic formation found in South China.

It was deposited on a shallow marine carbonate platform.

However, its small shelly fossils and Micrhystridium-like acritarchs are a shared characteristic with the Cambrian Yanjiahe Formation.
