Stony Run is a tributary of Buffalo Creek in Union County, Pennsylvania, in the United States. It is approximately 3.3 miles (5.3 km) long and flows through West Buffalo Township and Buffalo Township. The watershed of the stream has an area of 1.46 square miles (3.8 km2). The stream is impacted by nutrient pollution, sediment, E. coli, and thermal radiation. The watershed mostly consists of forested land and agricultural land. It is designated as a High-Quality Coldwater Fishery and a Migratory Fishery. The stream also has a healthy population of benthic macroinvertebrates.

Stony Run begins in West Buffalo Township. It flows east-southeast through a broad valley that it shares with Rapid Run. After more than a mile, the stream enters Buffalo Township. Here, it turns southeast for several tenths of a mile before receiving an unnamed tributary from the . It then turns southwest for several hundred feet before turning east-southeast again. After several tenths of a mile, it turns southeast and a few tenths of a mile after that, it reaches its confluence with Buffalo Creek.

Stony Run joins Buffalo Creek 9.68 miles (15.58 km) upstream of its mouth.

Stony Run is impacted by nutrient pollution, sediment, E. coli, and thermal radiation.

In 2000, the sediment load of Stony Run was 89,897 pounds (40,777 kg), while in 2008, it was 83,827 pounds (38,023 kg). This equates to less than 100 pounds per acre (110 kg/ha). However, the annual sediment load could in the future be reduced by 68.43 percent to 26,467 pounds (12,005 kg). In 2000, row crops and streambank erosion contributed 46,974 and 33,173 pounds (21,307 and 15,047 kg) of sediment, respectively. A total of 4,438 pounds (2,013 kg) came from hay and pastures, 2,710 pounds (1,230 kg) came from low-density urban land, and 2,602 pounds (1,180 kg) came from other sources.
