Pulpit Rocks is a geological formation adjacent to Pike Road northwest of Huntingdon in Huntingdon County, Pennsylvania. These weathered rock formations were instrumental in the determination of the stratigraphy of the Appalachian Mountains in the mid-19th century by the Pennsylvania Geological Survey. This work was influential in opening up new fields of geological research. The site was declared a National Historic Landmark in 1993. It is partially owned by Juniata College, whose geology department uses the site for educational purposes. A plaque marks its location.
