The Mesaverde Formation is a Late Cretaceous geologic formation.

The formation is described by W.G. Pierce as interbedded light gray sandstone and gray shale in upper part; lower part massive, light-buff, ledge-forming sandstone containing thin lenticular coal beds.[1]

The formation occurs in various structural basins in the western United States such as Piceance Basin, Powder River Basin, Uintah Basin, Washakie Basin, and Wind River Basin.

Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[2]
