Cut Bank Creek is a tributary of the Marias River, approximately 75 mi (123 km) long, in northwestern Montana in the United States.
It rises in the Rocky Mountains in Glacier National Park at the continental divide and flows ENE onto the foothills and plains of the Blackfeet Indian Reservation, then southeast, past Cut Bank. In southeastern Glacier County, approximately 12 mi (19 km) southeast of Cut Bank, it joins the Two Medicine River to form the Marias.
