Kase Run is a tributary of Mahoning Creek in Montour County, Pennsylvania, in the United States. It is approximately 4.6 miles (7.4 km) long and flows through West Hemlock Township and Valley Township. The stream's watershed has an area of 7.27 square miles (18.8 km2). The stream and a number of its tributaries are considered by the Pennsylvania Department of Environmental Protection to be impaired by siltation due to agriculture.

The rock in the watershed of Kase Run is of several rock formations, including the Wills Creek Formation, the Trimmers Rock Formation, the Catskill Formation, the Hamilton Group, and others. The soil series in the stream's watershed include the Leck Kill-Minersville-Calvin series and the Berks-Weikert-Bedington series. Kase Run may have been named after Abraham Kase. It is designated as a coldwater fishery.
