Swanks Run is a tributary of West Branch Fishing Creek in Sullivan County, Pennsylvania, in the United States.

Boulder Colluvium, alluvium, and bedrock consisting of sandstone and shale can be found in the vicinity of the stream.

After several tenths of a mile, the stream reaches its confluence with West Branch Fishing Creek.

[1] Swanks Run joins West Branch Fishing Creek 10.64 miles (17.12 km) upstream of its mouth.

However, it does have one unnamed tributary, which is slightly less than half a mile long and flows in a north-to-south direction.

In these areas, the majority of the surface is covered in boulders and cobbles consisting of quartz, sandstone, or conglomerate.
