Furnace Run is a tributary of Catawissa Creek in Columbia County, Pennsylvania, in the United States. It is approximately 2.5 miles (4.0 km) long and flows through Catawissa Township and Main Township. The stream is the last named tributary to enter Catawissa Creek before its mouth. The stream's watershed has an area of 2.82 square miles (7.3 $km^2).$ The main rock formations are the Pottsville Group and the Mauch Chunk Formation. The stream itself is considered to be a high quality coldwater fishery and Class A Wild Trout Waters.

## Course

After continuing northeast for a few tenths of a mile, it turns east-southeast. A short distance downstream, it receives an unnamed tributary and turns east-northeast and crosses a road. More than a mile further downstream, the stream reaches its confluence with Catawissa Creek.

Furnace Run joins Catawissa Creek 7.37 miles (11.86 km) upstream of its mouth.
