The Ash Hollow Formation is a geological classification for the middle strata of the Ogallala unit. The notable feature of this strata is the lenticular beds of white conglomerate stone that form landmark bluffs in the central High Plains of North America.

Formal use of this classification has been abandoned outside of Nebraska; however, the features of this material are observed throughout the region.
