, in the United States. It is approximately long and flows through Benton Township. The stream's watershed has an area of . Shale, sandstone, alluvium, and glacial till can be found in the watershed. At least one bridge crosses the stream. The stream is most likely named after Alexander Colley, Sr.

Course

Culley Run begins in a valley in Benton Township between Steinbuck Road and Cully Run Road. It flows southeast for several hundred feet, alongside Cully Run Road. It then turns east for a short distance and then turns south, still following the road. After a few tenths of a mile, the stream crosses

and turns east-southeast for several tenths of a mile, flowing alongside Pennsylvania Route 254. After several tenths of a mile, it crosses Pennsylvania Route 254 again. Several hundred feet further downstream, it reaches its confluence with Fishing Creek, not far from the community of Maple Grove. Culley Run joins Fishing Creek upstream of its mouth.

on August 2, 1979. Its identifier in the Geographic Names Information System is 1172817. In 2004, the Columbia County Natural Areas Inventory recommended protecting Culley Run. Culley Run is also known as Colley Run. Walter M. Brasch asserts in his 1982 book ''Columbia County Place Names'' that Colley Run is the correct name of the stream, although it is officially known as Culley Run. Brasch states that the stream is most likely named after Alexander Colley, Sr., a surveyor and teacher who served on the Pennsylvania legislature from 1822 to 1823.
