Prophetstown State Park is an Illinois state park on 53 acres (21 ha) in Whiteside County, Illinois, United States. Situated on south bank of the Rock River adjoining modern Prophetstown, Illinois, it was the site of a native American village founded by Ho-Chunk chief Wabokieshiek (also known as White Cloud) along the Sauk Trail and populated in the early 19th century by Native Americans of various tribes who did not wish to evacuate across the Mississippi River as whites emigrated to the area. It became a strategic target during the Black Hawk War. Illinois militia general Samuel Whiteside ordered the recently abandoned village burned on May 10, 1832.
