Brish Run is a tributary of Pine Creek in Luzerne County, Pennsylvania, United States. It is approximately 1.5miles long and flows through Fairmount Township. The watershed of the stream has an area of 0.66sqmi. The stream has one unnamed tributary. The surficial geology in the vicinity of Brish Run mostly consists of Wisconsinan Till, but there is alluvium near its mouth and also bedrock in the area. The stream is being considered for wild trout designation.
Brish Run begins in a relatively shallow valley in Fairmount Township. It flows south-southeast through the valley for a few tenths of a mile before gradually turning south. A short distance further downstream, it receives an extremely short unnamed tributary from the left and crosses Municipal Road.
