White Horse Hill National Game Preserve (Dakota: Šúŋkawakháŋ Ská Pahá, formerly known as Sullys Hill National Game Preserve) is a National Wildlife Refuge and nature center located on the shore of Devils Lake in Benson County, North Dakota, within the Spirit Lake Tribe reservation.

On March 3, 1931, during the Great Depression, the United States Congress transferred the park to be managed by the Fish and Wildlife Service as a wildlife refuge, where hunting is permitted with the Spirit Lake Tribe having both fishing and hunting rights.

In December 2019, the park was renamed through an act of Congress to its traditional Dakota name of White Horse Hill.

[3] In May 2019, the Spirit Lake Tribal council had requested the federal government change the name to White Horse Hill in cooperation with the governor's office and the North Dakota Department of Tourism stating, "The Spirit Lake Dakota people... believe the name chosen, White Horse Hill, comes from historical happenings that are sacred as well as unique to the Dakota people.

Open seasonally, the visitor center includes an exhibit hall of mounted North Dakota animals in prairie, wetland, forest, and agriculture habitats, education classrooms, and a book store.
