Scotch Run is one of the main tributaries of Catawissa Creek in Columbia County, Pennsylvania, in the United States. It is approximately 7.8 miles (12.6 km) long and flows through Beaver Township and Main Township. The stream's watershed has an area of 9.10 square miles (23.6 km2). The stream is infertile and acidic. It is 7.2 feet (2.2 m) wide in its upper reaches and 17.0 feet (5.2 m) wide in its lower reaches. The main rock formations in the watershed include the Mauch Chunk Formation, the Pocono Formation, the Pottsville Formation, and the Spechty Kopf Formation. The main soils include Leck Kill soil and Hazleton soil. It flows between Nescopeck Mountain and McCauley Mountain.
Nearly all of Scotch Run's length is within 1,640 feet (500 m) of a road. However, most of its length is not within 328 feet (100 m) of one. Part of Pennsylvania State Game Lands Number 58 is in the watershed and ephemeral natural pool system is located near the stream. The area in the vicinity of the stream was settled relatively late compared to the surrounding areas. The Pennsylvania Fish and Boat Commission carried out a survey of the creek in 1977. Scotch Run is designated as a Coldwater Fishery and a Migratory Fishery. In 1997, three species of fish were observed in the upper reaches of the stream, while eight species were observed in the lower reaches. Both reaches contained brown trout and brook trout. There is a hemlock-mixed hardwood palustrine forest along the stream.
Scotch Run begins in a lake in a valley in eastern Beaver Township. It flows west and slightly south for several miles between Nescopeck Mountain and McCauley Mountain. The stream eventually passes through the unincorporated community of Mifflin Cross Roads. Near this community, it turns south briefly before turning west-southwest again and flowing between Nescopeck Mountain and Dry Ridge. A short distance later, the stream exits Beaver Township and enters Main Township. In Main Township, it flows between Nescopeck Mountain and Full Mill Hill for slightly more than half a mile. It then reaches its confluence with Catawissa Creek.
