Aztalan State Park is a Wisconsin state park in the Town of Aztalan, Jefferson County, at latitude N 43° 4′ and longitude W 88° 52′. Established in 1952, it was designated a National Historic Landmark in 1964 and added to the National Register of Historic Places in 1966. The park covers 172 acres (0.7 km² or 70 ha) along the Crawfish River.
Aztalan is the site of an ancient Mississippian culture settlement that flourished during the 10th to 13th centuries. The indigenous people constructed massive earthwork mounds for religious and political purposes. They were part of a widespread culture with important settlements throughout the Mississippi River valley and its tributaries. Their trading network extended from the Great Lakes to the Gulf Coast, and into the southeast of the present-day United States.
