Stony Brook is a tributary of Fishing Creek in Columbia County, Pennsylvania. It is 4.3 miles (6.9 km) long and flows through North Centre Township and Orange Township. The stream's watershed has an area of 3.72 square miles. It flows through a steep ravine which is inhabited by numerous plant species for much of its length. The fossil-rich Stony Brook Beds also have an outcropping near the stream. In the 1870s, it was considered for use as a water supply by the Bloomsburg Water Company.
