Green Run (also known as Green Run Creek) is a tributary of Spring Brook in Lackawanna County, Pennsylvania, in the United States. It is approximately 4.7 miles (7.6 km) long and flows through Spring Brook Township, Roaring Brook Township, and Scranton. The watershed of the stream has an area of 4.32 square miles (11.2 km2). It is considered to be Class A Wild Trout Waters throughout its entire length. Numerous macroinvertebrate taxa also inhabit the stream. The surficial geology in the vicinity of the stream's lower reaches mainly consists of Wisconsinan Till, bedrock, and Boulder Colluvium.
Green Run begins in a pond near Tooley Corners in Spring Brook Township. It flows northwest for a few tenths of a mile and almost immediately enters Roaring Brook Township. It then turns west and crosses Pennsylvania Route 307 before turning southwest. Several tenths of a mile further downstream, it reenters Spring Brook Township and turns west-northwest, reentering Roaring Brook Township. The stream then turns west and enters Scranton. After a few tenths of a mile, it turns southwest and reenters Spring Brook Township. It flows generally in a westerly direction for a few miles in a deep valley near the border between Spring Brook Township and Scranton. The stream eventually turns south-southwest for several tenths of a mile and reaches its confluence with Spring Brook.
Green Run joins Spring Brook 6.48 miles (10.43 km) upstream of its mouth.
The concentration of alkalinity in Green Run is 17 milligrams per liter. In the 1970s, the Roaring Brook Sewage Treatment Plant discharged high levels of sewage into the stream after rains.
The elevation near the mouth of Green Run is 1,152 feet (351 m) above sea level. The elevation of the stream's source is between 1,640 and 1,660 feet (500 and 510 m) above sea level.
