First Peoples Buffalo Jump State Park is a Montana state park and National Historic Landmark in Cascade County, Montana in the United States. The park is 1,481 acres (599 ha) and sits at an elevation of 3,773 feet (1,150 m). It is located about 3.5 miles (5.6 km) northwest of the small town of Ulm, which is near the city of Great Falls. First Peoples Buffalo Jump State Park contains the Ulm Pishkun, a historic buffalo jump utilized by the Native American tribes of North America. It has been described as, geographically speaking, either North America's largest buffalo jump or the world's largest. There is some evidence that it was the most utilized buffalo jump in the world. The site was added to the National Register of Historic Places on December 17, 1974, and designated a National Historic Landmark in August 2015. The former name of the park was derived from the Blackfeet word "Pis'kun," meaning "deep kettle of blood," and the nearby town of Ulm.

A buffalo jump, or sometimes bison jump, is a cliff formation which Indigenous peoples of North America historically used to hunt and kill plains bison in mass quantities. The broader term game jump refers to a man-made jump or cliff used for hunting other game, such as reindeer.
