Fults Hill Prairie State Natural Area, also known as the Fults Hill Prairie Nature Preserve, is an Illinois Nature Preserve on 997 acres (403 ha) in Monroe County, Illinois, United States. A key feature of the preserve is a 532-acre (215 ha) hill prairie located on the east bluff of the Mississippi River overlooking the American Bottom near Fults, Illinois. The Fults Hill Prairie has been listed as a National Natural Landmark. 
The preserve is dominated by steep Mississippi River limestone bluffs and ravines. On top of the bluff lies a thick coating of windblown loess soil. This parcel of land has grown into a hill prairie of grasses and forbs characteristic of the tallgrass prairie, and varied by snatches of fire-resistant trees such as the bur oak. 
The upland or hill prairie was once the dominant ecosystem for much of the land that became the U.S. state of Illinois, the Prairie State. The state's Department of Natural Resources, which owns the prairie parcel, describes it as containing "the largest complex of the highest quality, essentially undisturbed loess hill prairies along the Mississippi River in Illinois."  Most of the prairie acreage that makes up this parcel apparently remained un- plowed during the pioneer years of the 1800s.
