The Wabaunsee Group is a Late-Carboniferous geologic group in Kansas, extending into Nebraska, Iowa, Missouri, and Oklahoma.^{[1] [2]} The unit is recognized in the subsurface by drillers in Colorado as Wabaunsee Formation.^[1]

In locations, some upper members are not present due to a series of erosions that occurred in late-Pennsylvanian time.^{[3] [4]}
