The Oriskany Sandstone is a Middle Devonian age unit of sedimentary rock found in eastern North America. The type locality of the unit is located at Oriskany Falls in New York. The Oriskany Sandstone extends throughout much of the Appalachian Basin.
The unit name usage by the U.S. Geological Survey (USGS) is the Oriskany Sandstone. Butts (1940) stated that the Oriskany Sandstone "corresponds exactly with the Ridgely Sandstone" and that the rules of stratigraphic nomenclature dictate that the name Oriskany Sandstone should be applied to these strata.
