Beaver Run is a tributary of County Line Branch in Northumberland County and Montour County, in Pennsylvania, in the United States. It is approximately 3.9 miles (6.3 km) long and flows through Lewis Township in Northumberland County and Anthony Township in Montour County. The watershed of the stream mostly consists of agricultural land. The watershed lies over rock of the Onondaga and Old Port Formation, the Keyser and Tonoloway Formation, and the Hamilton Group. It lies over soil of the Chanango-Pope-Holly series, the Hagerstown-Edom-Washington series, and the Watson-Berks-Alvira series. The stream experiences siltation and organic enrichment.

A. Joseph Armstrong described Beaver Run as "small and overgrown" in his book Trout Unlimited's Guide to Pennsylvania Limestone Streams.
