Crooked Run is a tributary of Catawissa Creek in Schuylkill County, Pennsylvania, in the United States. It is approximately 4.4 miles (7.1 km) long and flows through North Union Township. The watershed of the stream has an area of 4.24 square miles (11.0 km2). The stream is considered to be a High-Quality Coldwater Fishery and Class A Wild Trout Waters. However, it is impaired by atmospheric deposition. The main rock formations in the stream's watershed are the Mauch Chunk Formation and the Pocono Formation and the main soils are the Leck Kill soil and the Hazleton soil.
Crooked Run begins on Catawissa Mountain in North Union Township. It flows east-southeast for a few tenths of a mile before turning roughly east for some distance and eventually flowing off Catawissa Mountain. The stream then turns northeast and begins to skirt the edge of the mountain for more than a mile. It then turns north for a few tenths of a mile, crossing Raricks Road, before turning west and then north again, flowing parallel to Bunker Hill Road for a few tenths of a mile. Several tenths of a mile downstream, the stream reaches its confluence with Catawissa Creek, a few hundred feet from the border between Schuylkill County and Columbia County.
Crooked Run joins Catawissa Creek 20.20 miles (32.51 km) upstream of its mouth.
Crooked Run has one unnamed tributary.
The upper reaches of Crooked Run are considered by the Pennsylvania Fish and Boat Commission to be impaired for aquatic life by atmospheric deposition due to pH. The stream is infertile and acidic, with the potential to be affected by acidic precipitation. The pH of the stream ranges from 5.8 to 6.6 and the concentration of alkalinity ranges from 3 to 5 milligrams per liter. An alkalinity concentration of 16 milligrams per liter has been observed using methyl orange 0.81 miles (1.30 km) upstream of the stream's mouth. The total concentration of water hardness in the stream is 5 milligrams per liter 2.75 miles (4.43 km) upstream of its mouth and 10 milligrams per liter 0.81 miles (1.30 km) upstream of the mouth.
