The Utz Site, designated by the Smithsonian trinomial 23SA2, is a major Native American archaeological site in Saline County, Missouri, located on bluffs overlooking the Missouri River. Partially preserved in Van Meter State Park, it is the site of one of the largest early Contact Native villages in the region, which was occupied by the Missouri tribe from c. 15th to the late 18th centuries, and was probably the principal village area occupied by them at the time of their first contact with Europeans. The site was designated a National Historic Landmark in 1964.
