The township is located in southwestern Cumberland County, bordered to the south by Adams County. The entire township is situated within the South Mountain range of southern Pennsylvania. South Mountain proper forms a ridge the crosses the northern part of the township, while Piney Mountain runs parallel to it along the southern edge of the township. Between the two ridges is the valley of Mountain Creek, which flows northeast to Mount Holly Springs and is a tributary of Yellow Breeches Creek, which in turn flows to the Susquehanna River. Pine Grove Furnace State Park is located in the center of the township along Mountain Creek. The Appalachian Trail crosses the township, passing through the state park.

Jay Cooke was among the investors who in 1864 purchased the South Mountain Iron Company at Pine Grove Furnace,[6] a charcoal-fired iron operation dating to 1764. The specific reason that Cooke Township was created in 1872 out of previously existing Penn Township (established 1860) is unclear. Jay Cooke lost the company in the Panic of 1873, but bought back a major portion of it four years later with a group of investors as the South Mountain Mining and Iron Company.

Jay Cooke by Henry Shrady, Duluth, Minnesota

He was still a co-owner at the time of his death. According to the biography by Oberholtzer (who Cooke and his family assisted), Jay Cooke visited Pine Grove Furnace repeatedly. Cooke fished for trout there—he was an avid outdoorsman throughout his life—and he annually brought gifts such as pocket knives and scissors to the small school established there for the workers' children. Cooke Township continues to this day as a very lightly populated but heavily forested area, while the former center of the iron industry within it is now Pine Grove Furnace State Park.

The Pine Grove Furnace was added to the National Register of Historic Places in 1977.[7]
