Point of Rocks is an unincorporated community and census-designated place in Frederick County, Maryland, United States. As of the 2010 census it had a population of 1,466. It is named for the striking rock formation on the adjacent Catoctin Mountain, which was formed by the Potomac River cutting through the ridge in a water gap, a typical formation in the Appalachian Mountains. The formation is not visible from the town and can only be seen from boats on the river, or from the southern bank of the river in Virginia.
