Coal Run is a tributary of North Branch Buffalo Creek in Union County, Pennsylvania, in the United States. It is approximately 3.6 miles (5.8 km) long and flows through Lewis Township and West Buffalo Township. The watershed of the stream has an area of 5.33 square miles (13.8 km2). A few streams in its watershed are designated as impaired due to nutrients and siltation. The watershed mostly consists of agricultural and forested land. Wild trout occur within the stream.
Coal Run begins near a valley in Lewis Township. It flows southeast for several tenths of a mile before entering West Buffalo Township. Immediately upon entering that township, the stream turns east-southeast for several tenths of a mile, receiving one unnamed tributary from the . It then flows east for a few miles, receiving three more unnamed tributaries from the left. After a while, it turns east-southeast for a few tenths of a mile before turning east again and receiving another unnamed tributary from the left. The stream then flows east-northeast for several tenths of a mile until it reaches its confluence with North Branch Buffalo Creek.

Various tributaries to Coal Run are designated as impaired waterbodies. The cause of the impairment is nutrients and siltation, while the source is grazing-related agriculture. The total maximum daily load date is 2015. Streams in its watershed are also impacted by E. coli and thermal radiation. The stream and a number of others in Union County have been described as "not as clean as they should be".
In 2000, the load of sediment in Coal Run was 608,838 pounds (276,164 kg) and in 2008, it was 571,464 pounds (259,212 kg). This equates to between 150 and 200 pounds per acre (170 and 220 kg/ha) per year. However, in the future, it could be reduced by 61.76 percent to 218,504 pounds (99,112 kg) per year. In 2000, row crops and streambank erosion were the largest contributors of sediment, contributing 289,101 and 230,144 pounds (131,134 and 104,392 kg), respectively. A total of 56,742 pounds (25,738 kg) came from hay and pastures, 9,808 pounds (4,449 kg) came from unpaved roads, 5,639 pounds (2,558 kg) came from low-density urban land, and 17,404 pounds (7,894 kg) came from other sources.
