Buck Run is a tributary of West Branch Brandywine Creek in Chester County, Pennsylvania, in the United States. It is approximately 17.2 miles (27.7 km) long and flows through West Sadsbury Township, Sadsbury Township, Pomeroy, Highland Township, East Fallowfield Township, West Marlborough Township, and Newlin Township. The watershed of the stream has an area of 48.60 square miles (125.9 km2). Its named tributaries include Doe Run and Birch Run. The stream's waters are slightly alkaline and contain various dissolved metals and nonmetals. Rock formations of shale, sandstone, and limestone occur in the watershed. Three covered bridges and several other bridges have been build over the stream. Additionally, a number of mills historically operated along the stream. Mayflies, stoneflies, and caddisflies inhabit the vicinity of the stream. Additionally, trout inhabit the stream.
Buck Run begins south of State Hill in West Sadsbury Township. It flows southeast for several tenths of a mile, crossing Pennsylvania Route 10 and entering Sadsbury Township. The stream turns south, east, and south again, crossing U.S. Route 30. The stream then flows southeast for over a mile in a valley before turning south and flowing along the western border of Pomeroy. South of Pomeroy, it flows southeast on the border between Highland Township and East Fallowfield Township for a few miles before turning south and continuing to follow the border. In this area, the stream receives the tributary Birch Run. It then begins meandering east-northeast for several miles in East Fallowfield Township and West Marlborough Township. After this, the stream turns southeast and receives the tributary Doe Run. Birch Run then turns northeast and enters Newlin Township, where it flows south-southeast for several miles until it reaches its confluence with Brandywine Creek.
