The Ste. Genevieve Limestone is a geologic formation named for Ste. Genevieve, Missouri where it is exposed and was first described. It is a thick-bedded limestone that overlies the St. Louis Limestone. Both are Mississippian in age. The St. Louis Limestone is Meramecian and the Ste. Genevieve is the base of the Chesterian series.[1]

It is a primary producer in the Illinois Basin and has produced commercial oil and gas in Warren County, Kentucky.
