Catawissa Creek (colloquially known as The Cat) is a 41.8-mile-long (67.3 km) tributary of the Susquehanna River in east-central Pennsylvania in the United States. Its watershed has an area of 153 square miles (400 km).
The waters of Catawissa Creek are highly acidic, with a pH of 4.5, due to runoff from an abandoned mine in the creek's watershed. Catawissa Creek is smaller than the nearby Fishing Creek due to a lack of major tributaries.
