Chestnut Ridge is an elongate hill trending northeast-southwest in west-central Bedford County, Pennsylvania.
It is partially forested with rural homes, farms, and notably apple orchards.
Four small towns surround it: Schellsburg, New Paris, Fishertown, and Pleasantville.
The New Enterprise Stone & Lime Co., Inc. New Paris Quarry (inactive) is located on the northwest flank of the ridge.
Early Devonian Limestone of the fossiliferous Keyser Formation is quarried there.
